During transcription, the DNA sequence of a gene is transcribed into a complementary RNA molecule. This process occurs in the nucleus of a eukaryotic cell or in the cytoplasm of a prokaryotic cell. The enzyme RNA polymerase binds to the promoter region of the DNA strand and begins to unwind the double helix. It then reads the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides according to the base pair rule (A-U, C-G, G-C, T-A).
The end result of transcription is a single-stranded RNA molecule that is complementary to the DNA template strand. This RNA molecule is called messenger RNA (mRNA) and serves as a blueprint for protein synthesis during translation.

During transcription, DNA is copied into RNA in the nucleus of a eukaryotic cell or in the cytoplasm of a prokaryotic cell. The end product is a single-stranded mRNA molecule that serves as a template for protein synthesis.
