WBCS.LIVE practice question

Which highly specialized enzyme acts like molecular glue to join Okazaki fragments together during DNA replication?

Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. DNA polymerase
  2. DNA helicase
  3. DNA ligase
  4. RNA primase

Correct answer and explanation

Correct answer: DNA ligase

Explanation: āœ… Correct Answer: C) DNA ligase šŸ“š Explanation: During DNA replication, the lagging strand is synthesized discontinuously in short segments called Okazaki fragments. The enzyme DNA ligase catalyzes the formation of phosphodiester bonds between these disconnected fragments, seamlessly sealing the nicks and creating one continuous, solid strand of DNA.
