In the context of this material, which process copies the DNA sequence into a messenger RNA?

• A. Transcription
• B. Translation
• C. Replication
• D. Transduction

Answer: (A)

Transcribing DNA into messenger RNA is transcription. In this process, RNA polymerase binds to a gene's promoter, unwinds the DNA, and uses one DNA strand as a template to synthesize a complementary RNA molecule. The produced mRNA carries the genetic message from the nucleus to ribosomes in the cytoplasm, where it is read during translation to build a protein. Translation is the step that uses the mRNA to assemble amino acids, replication copies DNA to DNA for cell division, and transduction refers to DNA transfer via a virus, not RNA synthesis from DNA.
