"Given that DNA and RNA polymerases both carry out template-dependent nucleotide polymerization, it might be expected that the two types of enzymes would be structurally related. However, x-ray crystallographic studies of both types of enzymes reveal that, other than containing a critical Mg ion at the catalytic site, they are virtually unrelated to each other; indeed template-depen… " - Rna polymerase is what type of molecule
