Question

The enzyme that polymerises deoxyribonucleotides in 5' → 3' direction only is called ______.

विकल्प

• helicase

• primase

• DNA polymerase

• DNA ligase

Answer 1

The enzyme that polymerises deoxyribonucleotides in 5' → 3' direction only is called DNA polymerase.

Explanation:

DNA polymerase builds a new DNA strand by adding deoxyribonucleotides in the 5′ → 3′ direction. The other enzymes unwind DNA, make RNA primers or join DNA fragments.
