Which enzyme fixes the Okazaki fragments in the lagging strand?
|
|
Helicase
|
|
|
Polymerase
|
|
|
Ligase
|
|
|
Primerase
|
Explanation:
Detailed explanation-1: -During lagging strand synthesis, DNA ligase I connects the Okazaki fragments, following replacement of the RNA primers with DNA nucleotides by DNA polymerase .
Detailed explanation-2: -DNA ligase I is responsible for joining Okazaki fragments together to form a continuous lagging strand.
