Question

The Okazaki fragments in $DNA$ chain growth : -

• A. Polymerize in the 5'-to-3' direction and explain 3'- to 5' DNA replication
• B. Result in transcription
• C. Polymerize in the 3'-to-5' direction and forms replication fork
• D. Prove semi-conservative nature of DNA replication

Answer 1

Answer: (A)

Okazaki fragments in DNA are linked up by the enzyme DNA ligase. Replication alays ocur in 5′ - 3′ direction. Okazaki fragments synthesised on 3′ - 5′ DNA template, join to form lagging strand which grows in 3′ - 5′ direction.
