During Transcription

Question

During transcription,
A) the DNA strands replicate, producing four mRNA molecules.
B) each strand in the DNA molecule directs the production of an mRNA molecule.
C) a template strand of DNA directs the production of an mRNA molecule.
D) a template strand of DNA directs the production of a tRNA molecule.

Accepted Answer

During transcription, only one of the two strands in the DNA molecule, the template strand, is used as a guide to produce a complementary mRNA molecule. The other strand (non-template strand) is not used in the transcription process. Therefore, only option C accurately describes the process of transcription.
