The
complementary pairing of nucleotide bases explains how identical copies of
parental DNA pass on to two daughter cells This research launched a revolution
in biology that led to modern recombinant DNA techniques Complete hydrolysis of DNA (or RNA) yields a pentose sugar, phosphoric
acid and nitrogen containing heterocyclic compounds (called bases) In
DNA molecules, the sugar moiety is b-D-2-deoxyribose whereas in
RNA molecule, it is b-D-ribose
