Question

during transcription, a template strand of dna directs the production of an mrna molecule. the dna strands replicate, producing four mrna molecules. a template strand of dna directs the production of all of the trna molecules needed for producing the genes protein product. each strand in the dna molecule directs the production of an mrna molecule.

Explanation:

Transcription is the process where a DNA template strand is used to synthesize an mRNA molecule. DNA replication produces DNA, not mRNA. Also, tRNA is not directly produced from the DNA template in the way described in the third option. And only one strand (the template strand) is used to direct mRNA production, not each strand.

Answer:

a template strand of DNA directs the production of an mRNA molecule.
