Nucleic acids are necessary biomolecules as they function in the expression, transmission and storing of genetic information needed for the synthesis of proteins. They are responsible for passing on genetic information from one cell generation to the succeeding cell generation. These nucleic acids can be broken down into nucleotides, which are composed of a 5-carbon ribose sugar, an amine or nitrogenous base and a phosphate. The ribose sugars can be used to classify the two types of nucleic acids; namely DNA (deoxyribonucleic acid) and RNA (ribonucleic acid). The amines are classified as either a purine or pyrimidine. The purines are guanine and adenine while the pyrimidines are cytosine, thymine and uracil.
Deoxyribonucleic acid or DNA is a double helix composed of a pentose sugar and phosphate backbone ...

...NA fragments will consequently have an easier time moving through the gel mesh thus larger fragments will produce bands near the top of the gel while the smaller fragments can be found at the bottom.
Finally, the DNA can be visualized through staining and subsequent UV illumination. Two staining methods can be used, the first is rapid DNA staining through BioRad Fast Blast DNA stain solution, the second is through the use of ethidium bromide which is more sensitive than the first but is more dangerous since the main solution is a carcinogenic material.
In this experiment, however, restriction enzymes were not used such that the results showed little success, as judged by the lack of DNA bands in the agarose gels that were used to check the results sue to the isolated genomic DNA being so large that it does not migrate in the gel and instead remains in the well.

- I am writing to express my sincere interest in the postdoctoral ABMGG fellowship program in Clinical Biochemical Genetics at the University of Alabama at Birmingham (UAB). I am currently working at the department of Genetics at UAB as a research instructor and expect to finish my projects on the inherited disorder Neurofibromatosis type 1 (NF1) in the next few months. From my experience in both research and clinical settings, I have grasped extensive knowledge and skills in both areas of Human Genetics and Biochemistry that make me a strong candidate for the position....

- RESULTS Visualization of genomic DNA and PCR fragments in electrophoresis. To isolate genomic DNA from different bacterial cultures addition of enzymes was necessary to degrade the amino acid (RNA), proteins, and denature the cell. Briefly, DNA was isolated from four different bacterial types Rhodobacter sphaeroides 2.4.1, Rhodobacter sphaeroides 17029, Rhodopseudomonas palustris BisB5, and Escherichia coli. Agorose gel electrophoresis was performed to verify the presence of genomic DNA from the four different bacterial types (Fig.... [tags: DNA, Protein, Amino acid, Gene]

- The unique insight brought by the ENCODE project has lead to several revolutionary ideas for the inter workings of genetics on the molecular scale; however, there has been much controversy over the projects findings throughout the scientific community. The ENCODE project states “The vast majority (80.4%) of the human genome participates in at least one biochemical RNA-and/or chromatin-associated event in at least one cell type” (The ENCODE Project Consortium). This statement claims the functionality of the human genome as a whole and is the core theme that will be analyzed.... [tags: genome, evolutionary, dna]

- “The highest rated science program on TV called NOVA made a documentary surrounding genomic testing called, Cracking Your Genetic Code (NOVA, 2008).” This documentary demonstrated and described different techniques of what is genetic testing, how genetic testing is performed, and all the individuals whom benefit from these special DNA techniques. What is DNA. “DNA is material that governs inheritance of eye color, hair color and many other human and animal traits (Riley, 2005).” DNA is developed from the pairing of genes from a female and male gametes (Health & Prenancy, 2012)....

- Unique genetic makeup defines every person. This difference in the genetic makeup, caused mostly due to genetic variations, decides how a person will react to drugs or whether he/she is at risk of developing a disease or not (Glusman et al. 2011). The idea of Genomic medicine (Omenn 2013) can be applied to transform healthcare. Methods like genome sequencing, RNA-seq and predictive tools can be used to evaluate a person’s health risk and prepare health roadmaps to analyze the risk, prevent the advent of the disease and precisely treat it if it already occurred....

- Whole genome shotgun sequencing (WGS) is an effective method for the study of reference sequences in genomes. It generates several sequences data, which result in overlapping sequences eventually. The aligning DNA sequences achieved overlapping sequence assembly into contigs that could read through the computer program. The WGS method is not applicable when redundant repetitive sequences exist in large genomes1 (cited in 1). Several methods such as methylation-spanning linker libraries (MSLL), Methylation filtration (MF) and others have used eradicating redundancy in higher plant genomes that depended on the hypermethylation tendency of repetitive sequences....

- Transketolase is an essential component of many enzymatic, biochemical processes. According to the National Center of Biotechnology Information, in conjunction with a self-paraphrased definition, transketolase is a thiamine pyrophosphate, metabolic coenzyme which is partly responsible for various catalytic reactions, sucrose breakdowns and chemical, ketose transports. Albert L. Lehninger, Michael Cox and David R. Nelson, the authors of Lehninger Principles of Biochemistry, confirm this proposed definition in the works of their book (2005)....

- Enzyme Kinetics Enzymes are described as the organic catalysts, which increase the rate of reaction of a biochemical reaction. Enzymes are proteins that speed up the rate of reaction without being used up, and therefore they are reusable (Jonathan, 2012). The enzyme studied in this lab was succinate dehydrogenase. Enzyme kinetics is the study of how biological catalysts increase the reaction rate in reactions. Without the catalysts, the biological procedures necessary for organisms would not continue at a rate that could sustain life.... [tags: proteins, mitochondria, dna]
