Which Molecule Serves as the Template During Transcription

Question

Which molecule serves as the template during transcription?
A) DNA
B) mRNA
C) tRNA
D) polymerase

Accepted Answer

During transcription, the DNA molecule serves as the template for the synthesis of a complementary RNA molecule. The RNA polymerase enzyme binds to a specific region on the DNA known as the promoter, and uses one strand of DNA as a template to synthesize a single-stranded RNA molecule with a complementary sequence. This process is important for the expression of genes and the production of proteins in cells.
