Figure 1: A gene is expressed through the processes of transcription and translation. 1  During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink).
Confidence votes 261. Transcription is the synthesis of RNA under the direction of DNA. The type of RNA used during transcription is the messenger RNA. The mRNA carries a genetic message from the DNA to the protein-synthesizing machinery of the cell.Then, translation is the actual synthesis of a polypeptide, which occurs under the direction of mRNA.onfidence votes 261.
