In an overview of transcription, which enzyme is responsible for synthesizing RNA from a DNA template?

• A. DNA polymerase
• B. RNA polymerase
• C. Helicase
• D. DNA ligase

Answer: (B)

Verified step by step guidance

1. Understand the process of transcription, which is the synthesis of RNA from a DNA template.
2. Recall that transcription requires an enzyme to read the DNA sequence and build a complementary RNA strand.
3. Identify the enzyme responsible for this process; DNA polymerase synthesizes DNA, not RNA.
4. Recognize that RNA polymerase is the enzyme that binds to DNA and synthesizes RNA during transcription.
5. Note that helicase unwinds DNA and DNA ligase joins DNA fragments, but neither synthesizes RNA.
