Step one... helicases come in and break bonds between bases
step two... single binding proteins keep them apart
step 3.. RNA polymerase comes in and lays down new nucleotides on DNA strands
3 types of rna are... messenger, transfer, ribosomal
messenger/mRNA/mRNA___________... long chains of nucleotides in multiples of 3/codons
