<P> Transcription is the first step of gene expression , in which a particular segment of DNA is copied into RNA ( especially mRNA ) by the enzyme RNA polymerase . Both DNA and RNA are nucleic acids , which use base pairs of nucleotides as a complementary language . During transcription , a DNA sequence is read by an RNA polymerase , which produces a complementary , antiparallel RNA strand called a primary transcript . </P>
