What is the process by which DNA is copied into RNA?

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

Answer: (D)

Transcription is the process by which DNA is copied into RNA. In transcription, an RNA polymerase enzyme binds to a gene’s promoter and reads the DNA template strand, assembling a complementary RNA strand. It uses ribonucleotides, so adenine pairs with uracil (not thymine), and cytosine pairs with guanine. The resulting RNA copy can then be used to make proteins later through translation. This is different from replication, which copies DNA to DNA; and from translation, which converts RNA into a protein sequence; and from mutation, which is a change in the DNA sequence itself.
