Compare RNA-dependent RNA polymerase. RNA polymerase (RNAP or RNApol), also known as DNA-dependent RNA polymerase, is an enzyme that produces primary transcript RNA. In cells, RNAP is necessary for constructing RNA chains using DNA genes as templates, a process called transcription.
RNA and Protein Synthesis. During transcription, the enzyme RNA polymerase synthesizes a strand of messenger RNA (mRNA) using one strand of the gene as a template.mRNA is synthesized using nucleotides that contain the bases A, C, G, and U (instead of T), which pair with the complementary bases of the DNA template strand.uring transcription, the enzyme RNA polymerase synthesizes a strand of messenger RNA (mRNA) using one strand of the gene as a template.
