Adenine

The cyano-ethoxy carbonyl protection Manoharan et al. (1999) developed 2(cyanoethoxycarbonyloxy)succinimide S.27a a stable, crystalline, and convenient reagent for the protection of pendant akylamines in oligonucleotides (Figure X.X.X). The 2-cyanoethyl (ce) group is the most common phosphate protecting group in oligonucleotides; however, ce and corresponding 2-(cyanoethoxycarbonyl) group were not utilized for the nucleobase protection until 2000. Merk et al. (2000) developed 2-(cyanoethoxy)carbonyl (ceoc) protection for the protection of the excocylic amino group of adenine, guaninine, and cytosine. The (2-cyanoethoxy)carbonylation reactions were carried out with either 2-cyanoethyl carbonochloridate (S.27b ) or 1-((2-cyanoethoxy)carbonyl)-3-methyl-1H -imidazolium chloride (S.27c) (Figure X.X.X), which were synthesized by the…

Flow batteries have been around since the 1970’s this technological advance in the field of energy storage and acts as a fuel cell which can provide a new and efficient energy supply. One of the biggest advantages of flow batteries is that they can practically in an instance recharge just by replacing the electrolyte liquid,while this happens it is recovering the spent materials for recharge. Several different flow batteries have been developed, including Redox, Hybrid and, Membraneless. The…

Demonstration of Cellular Respiration Inside Lima Beans Cells in Vitro Purpose: Cellular respiration is a series of metabolic reactions that take place in the mitochondria and produce chemical energy in the form of ATP by the breakdown of food molecules.There are three processes involved in cellular respiration; glycolysis, the Krebs cycle and the electron transport chain. During this processes, glucose is oxidized by a series of redox reactions and its electrons and hydrogen ions are donated…

of the adenine pathway. The common yeast has the scientific name Saccharomyces cerevisiae. The eukaryote can grow as both haploid and diploid. The life cycle starts from an ascus undergoing “a” or “∝” haploid mitosis then undergoes the next stage of “a/∝” diploid mitosis where sporulation meiosis is then the final step before the life cycle repeats. There were two different strains of Saccharomyces cerevisiae, the “149 a” strain and the “176∝” strain. The 149a strain had the genotype of 149…

phosphate and deoxyribose backbone, and four different nitrogenous bases. These bases are adenine, guanine, cytosine, and thymine. Ribonucleic acid, the molecule formed in the transcription of DNA, is made up of phosphate, ribose, and adenine, guanine, cytosine, and uracil. The backbone of DNA consists of a phosphate bonded to a deoxyribose molecule. Deoxyribose is a sugar containing five carbons, and it is called deoxyribose as it is missing an oxygen atom on C2. The sugar found in RNA is…

tRNA models: cytosine, uracil, and adenine (CUA); cytosine, guanine, and guanine (CGG); adenine, uracil, and guanine (AUG). Anticodons were attached to their complementary codons using hydrogen bond connectors and each amino acid was bonded to its respective tRNA. The amino acid models were bonded together using the white bonding tubes. The amino acid sequence was detached and compared. All parts were detached and returned to bag. Results In this lab, a DNA model was constructed and then the…

The structure of DNA is a double helix, like a twisted ladder. The rungs each consist of two bases, either a pair of adenine and thymine, or a pair of cytosine and guanine, and the bases are shuffled, on different sides of the rings in a sequence. The sides of the of the 'ladder' are alternating sugars and phosphate groups. (Sugar-phosphate backbone) On one side of the ladder, the sugars are facing upwards, and on the other they are facing down. Each nucleotide has one deoxyribose sugar(without…

antiparallel. A purine must bond with a pyrimidine through hydrogen bonds. Hydrogen bonds are what keep the base pairs linked together throughout the DNA strand. Correspondingly, with two hydrogen bonds Adenine and Thymine are bonded and with three hydrogen bonds Guanine and Cytosine are bonded. DNA incorporates of a sugar- phosphate molecule backbone with nucleotides bonded down each side with peptide bonds. A nucleotide is made up of a deoxyribose sugar, phosphate molecule and a nitrogenous…

1. a) The three parts of a nucleotide are phosphate, nitrogen-containing base, and the deoxyribose sugar. b) Deoxyribose sugar is the sugar that is found in a nucleotide. c) The nitrogen-containing base is the nucleotide component that contains nitrogen. d) The four nitrogen bases shown in Model 1 are Adenine, Thymine, Guanine, and Cytosine. 2. a) I pointed at a single nucleotide on the ladder model of DNA, on the worksheet. The nucleotide included phosphate, nitrogen-containing base, and…

This paper is going to describe the replication of DNA and RNA and the processes of transcription and translation of protein synthesis. What is DNA? DNA is a nucleic acid that carries the genetic information in cells and some viruses, consisting of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. DNA sequences are replicated by the cell prior to cell division and may include genes,…
