Detailed explanation-1: -So, the correct option is ‘It uses the base thymine as a complement to adenine on RNA or DNA. ‘
Detailed explanation-2: -RNA in humans does not act as a genetic material but play various other roles such as an adapter, enzyme, helps in protein synthesis, etc. RNA functions as a messenger for information to be transferred.
Detailed explanation-3: -Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA.
Detailed explanation-4: -RNA is the genetic material for many viruses. Though bacteria show the presence of RNA, it does not act as the genetic material in them.
