Question

The letter X in the diagram below represents what enzyme used in the process shown?

A. DNA polymerase

B. helicase

C. ligase

D. RNA polymerase

Answer 1

Answer: Option D. RNA polymerase.

Step-by-step explanation:

• Transcription is the process which is used to produce RNA from a DNA template.
• The enzyme involved in the process of transcription is RNA polymerase which is responsible for separating the DNA strands and making an RNA which is complementary to the DNA.
• RNA polymerase joins the nucleotides in the newly formed RNA strands by utilizing the energy released from the cleavage of the additional phosphate bonds that are removed by it.
• The RNA polymerase dissociates from the DNA only after the process of transcription is complete.
