During Transcription, mRNA

A. Reads the genetic code

B. Provides the template

C. Plays catalytic role

D. All of the above

Answer: Option B

Solution(By Examveda Team)

During Transcription, mRNA provides the template.
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink).
The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.
