what enzyme synthesizes mrna from dna
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.he starting point for transcription, where RNA polymerase unwinds the DNA and begins to make a complementary mRNA copy, is the promoter site; the region of DNA that is the endpoint of transcription is the terminator site; mRNA is synthesized in the 5â to 3â direction.
