RNA polymerase synthesizes the RNA transcript during which stage of transcription?

• A. Elongation
• B. Initiation
• C. Replication
• D. Termination

Answer: (A)

Verified step by step guidance

1. Understand the three main stages of transcription: Initiation, Elongation, and Termination.
2. During Initiation, RNA polymerase binds to the promoter region of DNA and begins to unwind the DNA strands.
3. In the Elongation stage, RNA polymerase moves along the DNA template strand, synthesizing the RNA transcript by adding complementary RNA nucleotides.
4. Termination occurs when RNA polymerase reaches a termination signal, causing it to release the newly made RNA transcript and detach from the DNA.
5. Therefore, the stage during which RNA polymerase synthesizes the RNA transcript is Elongation.
