Which option best describes how mRNA is produced in a cell during DNA transcription?
A
DNA polymerase copies the entire genome into mRNA by adding DNA nucleotides to the 3′ end of the growing strand.
B
Ribosomes read DNA directly in the nucleus and assemble mRNA from amino acids before export to the cytoplasm.
C
RNA polymerase binds a gene’s promoter, unwinds the DNA locally, and synthesizes a complementary RNA strand using one DNA strand as the template.
D
RNA polymerase joins amino acids together to form mRNA using the coding strand of DNA as the direct template.
