Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which enzyme seals the fragments of DNA into a continuous strand?
A
DNA Ligase
B
DNA Polymerase
C
Helicase
D
Exonuclease
Explanation: 

Detailed explanation-1: -The enzyme that functions to seal the gap between the Okazaki fragments to create a continuous strand is d. Ligase (or DNA ligase). This enzyme works on the lagging strand (since there are no Okazaki fragments in the leading strand) joining together the Okazaki fragments generated by DNA polymerase III.

Detailed explanation-2: -Finally, an enzyme called DNA ligase? seals up the sequence of DNA into two continuous double strands.

Detailed explanation-3: -If two DNA molecules have matching ends, they can be joined by the enzyme DNA ligase. DNA ligase seals the gap between the molecules, forming a single piece of DNA.

Detailed explanation-4: -Once the fragments are made, DNA ligase connects them into a single, continuous strand.

Detailed explanation-5: -DNA ligase joins the Okazaki fragments together into a single DNA molecule. Helicase opens up the DNA at the replication fork.
