Nucleic acids

Biosynthesis of Nucleic Acids Page Break How in the world did the nucleic acid come from and how was it discovered is the question. Well, in 1869 a biochemist by the name Johann Fredrich Miescher (1844-1895) that was Swedish discovered nucleic acids. While biochemist Miescher was looking at cells he saw that there was an odd organic compound in the nucleus. With Miescher seeing this compound he named it nuclein. The organic compound was unique because it had phosphorus and nitrogen in it.

Proteins are biological molecules like nucleic acids and polysachharides. These are important parts of living organism. They play their essential roles in all the reactions and processes that occurring in the cells. As these are very important, these are vital for metabolism. Most proteins work s enzymes and catalyze all biochemical reaction occurring in living body(Lehninger et al.). Understanding for the molecular diseases has been improved after the successful accomplishment of human genome project

Unit Title: Biochemistry of Nucleic Acids (A.C. 5.1 and 5.2) The human body is made up of trillions of cells and each cell has a nucleus, filled inside with chromosomes made of a long string of DNA (deoxyribonucleic acid) wrapped around a special protein called histone (American cancer society 2014). According to Cancer Research UK (2014) DNA by itself is made up of thousands of genes, which are a coded message that tell the cell how to behave and divide. As such if the signals are missing, cells

Nucleic acid sequence-based amplification (NASBA) assay involves the non-PCR based amplification of viral RNA of all four dengue virus serotypes using universal primers at 41°C and to type the amplified products by serotype-specific capture probes by electrochemiluminescence (Wu et al. 2001). The method is unique in its cost effectiveness, 98.5 % sensitivity, 100 % sensitivity and short time of one day for investigation (Usawattanakul et al. 2002). Viral RNA detection using RNA guided clustered regularly

Arlet Morera Castillo Paper 1 Title: BIOLOGICALLY IMPORTANT MOLECULES, Carbohydrates, Proteins, Lipids, and Nucleic Acids. This paper will describe the importance of various organic molecules when we follow perquisite steps to unveil them in a few conducted tests. List of Authors: Arlet Morera Castillo Introduction: It is beneficial for us humans to start an early knowledge of the molecules that compose the things surrounding us and even ourselves. Scientifically that eagerness to comprehend

Introduction In recent years it has been found that prokaryotes, mainly bacteria and Achaea, contain an immune system that allows them to defend themselves against the nucleic acids that are integrated by viral genomes. Therefore, this discovery was made by studying the genomes of bacterial cells; which shed light on the clustered regularly interspaced short palindromic repeats (CRISPR) identified in many bacterial genomes. Therefore, the identification of CRISPR was first discovered in 1987 but

Food is made up of four types of organic compounds: carbohydrates, proteins, lipids, and nucleic acids. As food is ingested, the beginning stage of the digestive system is the first mechanical process of breaking down of foods in the mouth. Food is chewed, moistened and softened by saliva, and made into a bolus for swallowing. Saliva, made of mostly water, comes from intrinsic and extrinsic salivary glands. These salivary glands are exocrine glands that are activated by impulses sent by the facial

sugar and phosphate groups Because nucleic acids are polymers of individual nucleotide monomers. Each nucleotide has three parts which are 5 carbon sugar, a phosphate group and a nitrogenous base. 2) A) Glycerol + 3 fatty acids Because 3) B) has changed parts of its structure Because “a steroid hormone that stimulates development of male secondary sexual characteristics, produced mainly in the testes, but also in the ovaries and adrenal cortex.” 4) D) Amino Acids Because in a mammals liver cells

Abstract: In this experiment, it was attempted to purify acid phosphatase from wheat germ in its native confirmation with retention of enzymatic activity. The fraction that would contain the purified acid phosphatase (Supernatant IV), had 4.0mg of total protein, but no enzymatic activity and 0% recovery. The experiment was not successful. Acid phosphatase was not purified in its native confirmation with retention of enzymatic activity. In part 2c of the experiment, an error was made in the amount

how our body breaks down protein into amino acids. Water is used to break protein down in to its amino acids. Condensation- Condensation is when two molecules combine and form one bigger molecule. It is exact opposite process of hydrolysis. It is also
