Nucleic acids play a significant role in this process. A and G are categorized as purines, and C, T, and U ⦠Nucleotides are held together by peptide bonds. Professor and Head The functions of nucleic acids have to do with the storage and expression of genetic information. A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar (pentose), and at least one phosphate group With all three joined, a nucleotide is also termed a ânucleoside phosphateâ. ⢠Huge organic molecules that contains C, H, O, N, & P. ⢠Nucleic acid is a polymer of NUCLEOTIDE held by 3â and 5â phosphate bridges. Although nucleic acid chemistry appears to be a mature part of organic and bioorganic chemistry, the many questions that are still being raised by research in biology and chemical biology give sufficient motivation to continue to synthesize new nucleic acid probes and thereby further develop nucleic acid chemistry⦠If you continue browsing the site, you agree to the use of cookies on this website.

Introduction:
Frederic Miesher in 1869, isolated an acidic compound from the nuclear material of SALMON sperms, and named it as NUCLIEN which is now called NUCLEIC ACID.
Jones in 1920 proved the fact there are two types of nucleic acids, i.e., Deoxyribo nucleic acid (DNA) and Ribonucleic acid ⦠Viral infections can pose a mild risk to our health, like the common cold, or a threat to our lives, like an HIV infection. Each nucleotide has three components: 1. Indian medical graduate - goals, roles and competencies, Acid base balance - Regulation of pH of body fluids, No public clipboards found for this slide.

He found it behaved as an acid, so the material was renamed nucleic acid. A free online book on the chemistry and biology of nucleic acids, written by Prof. Tom Brown and Dr Tom Brown (Jnr). R.C. Objectives By the end of lecture the student should: Define nucleic acids. Three of the nitrogen bases are the same. Nucleic acid is an important class of macromolecules found in all cells and viruses. Structure of Nucleic Acids. Five-carbon-ring sugar (deoxyribose or ribose) 2. Chapter 22. Gupta He reported finding a weakly acidic substance of unknown function in the nuclei of human white blood cells, and named this material \"nuclein\".
