Primary Transcript
Detailed information:
When a gene is transcribed in the nucleus, the initial product is the primary transcript—an RNA containing copies of all exons and introns. This primary transcript is then processed by the cell to remove the introns, to cleave off unwanted 3′ sequence, and to polyadenylate the 5a end. The mature message thus formed is then exported to the cytoplasm for translation.
