RNA
Introduction: RNA, shortening of ribonucleic corrosive, complex compound of high atomic weight that capacities in cell protein union and replaces DNA (deoxyribonucleic corrosive) as a transporter of hereditary codes in some infections. RNA comprises of ribose nucleotides (nitrogenous bases annexed to a ribose sugar) joined by phosphodiester bonds, shaping strands of shifting lengths. The nitrogenous bases in RNA are adenine, guanine, cytosine, and uracil, which replaces thymine in DNA. The ribose sugar of RNA is a cyclical structure consisting of five carbons and one oxygen . The presence of a chemically reactive hydroxyl (−OH) group attached to the second carbon group in the ribose sugar molecule makes RNA prone to hydrolysis . This chemical lability of RNA, compared with DNA, which does not have a reactive −OH group in the same position on the sugar moiety (deoxyribose), is thought to be one reason why DNA evolved to be the preferr...
