Question

Choose the components that are required for the proper functioning of DNA polymerase enzyme.

(P) DNA template

(Q) A DNA primer

(R) An RNA primer

(S) Four different dNTPS

Options

• Only (P), (Q) and (R)

• Only (P), (R) and (S)

• Only (Q), (R) and (S)

• Only (P), (Q) and (S)

Answer 1

Only (P), (R) and (S)

Explanation:

• DNA Template (P): Needed to direct the new strand’s sequence.
• Primer (R): DNA polymerase is unable to begin a new strand from the beginning. An RNA primer (R) is used in natural replication (in vivo).
• dNTPs (S): These are the energy-producing building blocks (dATP, dTTP, dGTP, and dCTP).
