RNA is a multifaceted molecule. “RNA is an intermediary, carrying genetic information from the DNA to the machinery of protein synthesis” (Goodsell, 2003). The enzyme RNA polymerase creates different RNA molecules. RNA polymerase is made up of several proteins and they work together to surround DNA strands, unravel them and build an RNA strand based on the information inside the DNA. RNA polymerase needs to be accurate in its copying of genetic information and its production of a successful RNA strand. RNA polymerase is essential to the life of a cell and it can be very sensitive to poisons or toxins. One of the most powerful of these poisons is the alpha-amanitin. This is a peptide created by the death cap mushroom. If ingested the death cap mushroom can lead to a coma or death in just a few days. The poison of the alpha-amanitin attacks RNA…...

...Final Essay The chemistry 1100 class has been a very useful tool in helping me decide what I want to do with my life after college. Like most of the students in the biochemistry department, I had already firmly decided that I wanted to go to medical school after I graduate and eventually become a doctor and make money. What this class has helped me realize is that there are many more opportunities out there in the workforce that could be just as fulfilling and still be able to make enough income to live a comfortable lifestyle and help pay off student loans and provide for my family etc. Before taking this class I had a preconceived idea that research is boring and repetitive. I thought that all scientists did was stay confined in a lab all day working with test tubes and chemicals trying to find a solution problems. I was sure that I did not want to spend the rest of my life stuck in a lab trying to figure out an abstract idea. The reason why I wanted to become a doctor was because I wanted to do something that would make a difference in the lives of other people. What this class did for me was to open my eyes to a whole new opportunity to make a difference in the world and to prove that the stereotype that I had of research was wrong. I enjoyed that the biochemistry faculty took the time out of their busy lives to come and talk about their research and why they are doing what they are doing. From these speakers I was exposed to the vast opportunities there are for......

...DNA & RNA DNA Replication is semi conservative; meaning each strand of DNA is a template for new strands of DNA. DNA helicase is an enzyme that starts the process of DNA replication by opening the double helix stranded unwinding it. The Single stranded binding protein helps prevent DNA from attaching during the replication process( Hudon-Miller, 2013). DNA polymerase III is an enzyme that produces new strand, only reads in the 3’ to 5’ and adds new DNA strand in the 5’ to 3’ direction by forming replication bubbles and attaching at each replication fork. Because it can only add nucleotides to the 3’ direction there would be 2 different kinds of replication stands. The leading strand would be continuous towards the replication fork needing 1 RNA primer to initiate synthesis and the lagging strand would be fragmented away from the replication fork needing RNA primer to synthesize multiple times. Once RNA primer completes synthesis in the new DNA strand, DNA polymerase I fills the fragments with new nucleotides. DNA ligase is part of the last step of DNA. Its enzymes seal the Okazaki fragments together in creating a new DNA strand (Ahern & Rajogopal). In order to create new proteins for our bodies to perform its functions, DNA would have to go through a process called Transcription. Transcription is a process in which DNA is copied by mRNA. This takes place in the nucleus of the cell.DNA uses the help of RNA polymerase II which is an enzyme that initiates the......

...Transform with DNA and RNA Shelley Gutierrez, RNC Western Governors University Student ID: 391502 Sgutie6@wgu.edu How Cells Transmit Information and Transform with DNA and RNA All of our body cells are made up of 46 chromosomes. Each of the 46 chromosomes contains one DNA molecule. These chromosomes and proteins are found compressed in the nucleus of the cells. DNA and RNA are biological molecules that are nucleic acids. Both DNA and RNA are polymers. When polymers are linked together in DNA, they are called polynucleotides (Devlin, T. 2002). The polymers of DNA, known as nucleotides are composed of a phosphate group, 5 carbon sugar molecules, and 1 of 4 nitrogen bases. The four nitrogenous bases: adenosine, thymine, cytosine and guanine is where the genetic coding is found. DNA has twin molecules that twist together. This is known as the double helix. The double helix bonds with sugars and phosphates to form twin Strands. Chemically the sugar phosphate bonds travel down each side of the helix in opposite directions. One strand begins at the top of the 1st phosphate connected at the sugar molecules 5th carbon and ending where the next phosphate would go with the free end at the sugar’s 3rd carbon. This results in a pattern of 5 prime and 3 prime. The opposite occurs with the other strand resulting in a pattern of 3 prime and 5 prime. (Adams, R., & Knowler, J. 1986). Once they are bonded they are now known as base pairs. RNA and DNA......

...ASSIGNMENT 1: PROPERTIES OF DNA/RNA Introduction: The polymerase chain reaction is an innovative technology, which amplifies a single piece of DNA across several orders of magnitude. The end result is the creation of thousands to millions of copies of a particular DNA sequence. PCR is closely patterned after the natural principle of DNA replication. It is a three-step process, referred to as a cycle, that is repeated a specified number of times. One PCR cycle consists of the following steps: * Denaturation * Annealing * Extension This process takes place in a thermal cycles, usually between 30 and 40 cycles. In the initial step, heat (usually hotter than 90 degrees Celsius) separates double-stranded DNA into two single strands. This process is called "denaturation." Denaturation is possible because the hydrogen bonds linking the bases to one another are weak. The hydrogen bonds break at high temperatures, whereas the bonds between deoxyribose and phosphates, which are stronger covalent bonds, remain intact. The goal of PCR is not to replicate the entire strand of DNA but to replicate a target sequence of approximately 100-600 base pairs unique to the organism being studied. Targeting the sequence is achieved by using primers. They are specific for the target region of the organism. Two primers are included in the PCR, one for each of the complementary single DNA strands that was produced during denaturation. The primers that anneal or in......

Death Cap Mushrooms The Death Cap Mushroom is an extremely toxic mushroom that is responsible for the majority of the mushroom poisoning deaths in the world. This fungi is also known as Amanita phalloides and is mainly found in Europe. It is found growing on the ground in woodlands and mountains. This particular fungi contains two types of toxins, both are “ring-shaped peptides.” These toxins are amatoxins and phallotoxins and they target mainly the liver of the human body when ingested. RNA polymerase II is an essential enzyme in helpingour bodies produce messenger RNA (mRNA) as well as other RNA’s. The virulent function of the mushroom acts by stopping the movement of RNA polymerase II, transcription does not occur and therefore it does not produce mRNA. The amatoxin impedes RNA polymerase at both the initiation and the elongation phase. The translation phase will not happen now due to there being no mRNA available to make proteins. Protein synthesis cannot happen, cell metabolism stops and so the cell dies. After human consumption of the mushroom, it initially can cause nausea and vomiting, but soon it affects the liver. The liver is the first organ to be damaged then the kidneys. Electrolyte imbalances begin and there would be no proteins like collagen to help with cell......

DNA is a double strand and RNA is a single strand. Although DNA and RNA both carry genetic information, there are quite a few differences between them. The following information will describe the differences between DNA and RNA DNA DNA contains long-term storage of genetic information; transmission of genetic information to make other cells and new organisms. DNA is a double strand that has a long chain of nucleotides. DNA has a composition of bases and sugars. They are deoxyribose sugar, phosphate backbone, adenine, guanine, cytosine, thymine bases. DNA is also self-replicating. DNA has adenine-thymine also known as AT and guanine-cytosine also known as GC. DNA has a bond that make it very stable. The bond is a C-H bond. DNA has small grooves that serve as protection and minimal space for enzymes to attach to the strand its self. DNA is vulnerable to Ultraviolet that would cause damage to the strand. RNA RNA transfers the genetic code from the nucleus to the ribosome and that produces proteins. RNA transfers genetic information in some specimens. RNA in some cases is what molecule was used to store genetic blue prints in prime organisms. RNA is a single strand and the helix consists of short chains of nucleotides.

The forces, bonds, and interactions by protein structures at the Tertiary level. There are Hydrophobic (nonpolar), Ionic bonds, Hydrogen (covalent) bonds, and Disulfide bonds, also called Disulfide Bridges. Hydrophobic are nonpolar bonds, meaning they cannot interact with water or aqueous solutions. Hydrophobic interactions will cause the protein to change shape to avoid making contact with such solutions. Considered weak bonds, but the proteins cluster tightly together on the interior of the protein, Van der Waals interaction take place between the proteins, again these are the weakest of the molecular bonds. Ionic Bonds are by definition bonds that are made up of charged particles. There are 20 Amino Acids, some with negatively charged terminals, some with positively charged terminals. This is a basic chemistry property that opposites attract. These are considered stronger bonds, but not the strongest. Next are hydrogen bonds. Considered stronger bonds than hydrophobic bonds, but weak compared to ionic and disulfide bonds. Hydrogen bonds are formed from Polar Covalent interactions. Two amino acids share a hydrogen electron and connect on the second amino acid oxygen atom. There must be a hydrogen donor on one amino acid, and a hydrogen acceptor on a second amino acid to complete the bond. The......

...PNA is a nucleic acid that enters DNA's major groove to form a triple-stranded structure. This molecule can attach itself to a gene, and either prevent the RNA polymerase from transcribing the gene, or promote transcription by exposing some of the single-stranded DNA to transcription-initiating enzymes. This action can be very useful as a gene therapy in patients who are producing too much, or not enough of a certain protein. Another prospect of this mysterious molecule is the creation of artificial life. All of the organisms on earth are based on DNA and RNA, so the idea of creating life with only PNA is very intriguing to scientists. The major problem with this idea is that because the PNA is so stable, it is very difficult for it to split into two daughter strands. In reading this article, I learned that DNA and RNA are not the only existing nucleic acids. They are the only natural ones, but many more synthetic/artificial nucleic acids have been discovered, including PNA. I think that the implementation of PNA into drugs that regulate gene expression will be a major advancement in the field of molecular genetics. This molecule has the potential to regulate the symptoms of many genetic diseases, a huge step forward in the lives of those affected by genetic diseases. The one ethical issue surrounding PNA is the use of this molecule to create artificial life. The results of such an experiment are anyone's guess, and even though an outcome is still very far in the distance,...

... Nucleic Acids: There are two kinds of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is found largely in the nucleus of the cell, thus the general name, nucleic acid. (RNA is also found in the nucleus, though it is also present in the cytoplasm in large amounts.) Certain organelles also contain DNA (mitochondria and plastids). DNA and RNA are responsible for storing and implementing the genetic information in the cell. We will describe DNA, then characterize the differences between DNA and RNA. a) DNA is a double polymer of smaller molecules called nucleotides. A nucleotide consists of one sugar (deoxyribose for DNA), a phosphate functional group, and one of four molecules called nitrogenous bases. The two nucleotide polymers are connected together via hydrogen bonding between complementary base pairs. Here is a schematic representation of DNA structure |[pic] | In real space, the double polymer is twisted into a double helix b) The nucleotides in each polymer are covalently bonded together into a sugar-phosphate backbone. The nitrogenous bases are not involved in this backbone. c) In DNA, there are four different nitrogenous bases. (There is a fifth which is found only in RNA.) These bases come in two types, purines and pyrimidines. Purines consist of two interlocking......
