WebLike DNA polymerase, RNA polymerase adds nucleotides one by one to the 3′-OH group of the growing nucleotide chain. One critical difference in activity between DNA polymerase and RNA polymerase is the requirement for a 3′-OH onto which to add nucleotides: DNA polymerase requires such a 3′-OH group, thus necessitating a primer, whereas RNA … WebDNA is a working molecule; it must be replicated (copied) when a cell is ready to divide, and it must be “read” to produce the molecules, such as proteins, to carry out the functions of …
