उत्तर
A mRNA molecule is produced by transcription.
Explanation:
mRNA is synthesised from a DNA template during transcription. RNA polymerase makes a complementary single-stranded mRNA from one DNA strand. Replication makes copies of DNA, duplication is not the standard term for mRNA synthesis, and translation uses mRNA to build proteins.
