Difference between dna pol 1 and 3

http://www.differencebetween.net/science/health/difference-between-dna-polymerase-1-and-3/ WebTranscription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription has three stages: initiation, elongation, and termination.
