Which enzyme is responsible for RNA synthesis?

RNA synthesis is performed by an enzyme called RNA polymerase. Synthesis begins when the RNA polymerase approaches the promoter gene, produces a single-stranded DNA template, and starts to move along the strand of DNA toward the operator region.

RNA synthesis is the process of transcribing DNA nucleotide sequences into corresponding RNA sequences. The synthesis of RNA proceeds in much the same way as the replication of DNA. RNA polymerase moves along the open DNA molecule, copying one of the two strands base by base. After synthesis is complete, the RNA separates from the DNA strand, leaving a newly formed sequence that is complementary to the existing DNA code.
