Two enzymes that have been found in the isolated nucleus are DNA polymerase that catalyzes the synthesis of nucleotide polymers to form DNA and RNA polymerase, which does the same thing for RNA. WebJul 19, 2024 · The big difference is at the G nucleotide. It has the sugar in the C3' endoconformation (like A-form nucleic acid, and in contrast to B-form DNA) and the guanine base is in the synconformation. This places the guanine back over the sugar ring, in contrast to the usual anticonformation seen in A- and B-form nucleic acid.
