Which enzyme is responsible for synthesizing RNA using a DNA template?

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

Answer: (C)

Verified step by step guidance

1. Understand the process of transcription, where RNA is synthesized from a DNA template. This is a key step in gene expression.
2. Identify the role of RNA polymerase, which is the enzyme responsible for catalyzing the synthesis of RNA from a DNA template during transcription.
3. Differentiate RNA polymerase from other enzymes such as DNA polymerase, which synthesizes DNA, and ligase, which joins DNA fragments.
4. Recognize that helicase is involved in unwinding the DNA double helix, but does not synthesize RNA.
5. Conclude that RNA polymerase is the correct enzyme for synthesizing RNA using a DNA template, as it reads the DNA sequence and assembles the corresponding RNA strand.
