How does gene transcription work
WebFeb 13, 2014 · Transcription is the process of making an RNA copy of a gene sequence. This copy, called a messenger RNA (mRNA) molecule, leaves the cell nucleus and enters the cytoplasm, where it directs the synthesis of the protein, which it encodes. Here is a more complete definition of transcription: Transcription WebIn other words, there is a one-to-one correspondence of bases between the gene and the mRNA transcribed from the gene (excepting 5′ and 3′ noncoding regions).

The three stages of transcription involve various functions of RNA polymerase that result in the synthesis of RNA: 1. Initiation begins when RNA polymerase wraps around the promoter region of DNA. The promoter is a DNA sequence that guides RNA polymerase on where to bind upstream of a gene.
