Answer:
The correct answer is:C. One strand of DNA is used as a template to produce a complementary strand of mRNA.
Step-by-step explanation:
In transcription, an RNA chain is synthesized from the DNA sequence of a gene. RNA polymerases are involved, which bind nucleotides in the 5 'to 3 direction to form the RNA chain. Then, if this molecule is generated it is called pre-mRNA and then undergo processing and generate a messenger RNA (mRNA).
