What is the process of transcription?

Explanation:
Transcription is the process where the information encoded in DNA is copied into a complementary RNA molecule. RNA polymerase binds to a gene’s promoter, unwinds the DNA, and synthesizes an RNA strand in the 5' to 3' direction using the DNA template. The RNA bases pair with the DNA bases (A with U, T with A, G with C, C with G), producing an mRNA transcript that carries the genetic message to the ribosome. This mRNA will later be used in translation to build a protein. Transcription is not about making a protein directly, and it is not DNA replication or translating mRNA into amino acids. In eukaryotes, the initial transcript is often processed into mature mRNA before it leaves the nucleus.
