The Chemical Nature of DNA and RNA The backbone of a nucleic acid is made of alternating pentose ‘sugar’ (deoxyribose sugar in DNA and ribose sugar in RNA) and ‘phosphate’ molecules bonded together in a long chain. Each of the sugar groups in the backbone is attached to ‘nitrogenous base’. The ‘2′-deoxy-’ notation means that […]
DNA In most living organisms (except viruses), the genetic information is stored in the molecule called deoxyribonucleic acid or DNA. DNA is made and it resides in the nucleus of the living cells. The name DNA was derived from the sugar molecule contained in its backbone—deoxyribose. The high molecular weight nucleic acid, DNA, is found […]
The complex systems of living organisms encompass hundreds to thousands of proteins that exist help us to carry out our daily functions. The information required to manage this complex system is stored in a set of molecules called ‘nucleic acids’. The three most abundant biological macromolecules are ‘proteins’, ‘nucleic acids’ and ‘polysaccharides’. The information-carrying molecules […]
