Solution
The term for pre-mRNA when transcribed from a protein-coding gene is "primary transcript".
Here's a step-by-step explanation:
-
Transcription begins in the cell nucleus, where the DNA molecule is opened and unwound by the enzyme RNA polymerase at the location of the gene.
-
The RNA polymerase binds to a promoter region on the DNA and begins to synthesize an RNA molecule, using one of the DNA strands as a template.
-
This initial RNA molecule is known
