Transcription Steps 1 In the nucleus of epithelial cell the DNA is present which contains gene that codes for RNA molecule to make aquaslickin protein This region has promoter and the end site terminator It also contains regulatory sequences DNA is used as a template to make RNA with the help of RNA polymerase 2 Promoter region of DNA functions as a recognition site for polymerase as polymerase binds it unwinds the DNA as the initiation process 3 During elongation RNA polymerase slides on the template DNA stand as complimentary bases pair up RNA polymerase links nucleotide to the 3 end See Answer
