Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Known as the gluer, this enzyme glues DNA fragments together during the lagging stage.
A
ligase
B
primase
C
DNA polymerase
D
helicase
Explanation: 

Detailed explanation-1: -Hint: DNA ligase is also called “molecular glue”. During DNA replication, It attaches the Okazaki fragments formed from the lagging strand during the replication of DNA. It is the enzymes that are commonly used in genetic engineering.

Detailed explanation-2: -DNA ligase is a type of enzyme that facilitates the joining of DNA strands together by catalyzing the formation of a phosphodiester bond.

Detailed explanation-3: -The strand with the Okazaki fragments is known as the lagging strand. As synthesis proceeds, an enzyme removes the RNA primer, which is then replaced with DNA nucleotides, and the gaps between fragments are sealed by an enzyme called DNA ligase.

Detailed explanation-4: -DNA Ligase is the enzyme which helps in joining the fragments of DNA, basically, it acts as a glue.

Detailed explanation-5: -Transglutaminase (TG), aka Meat Glue, is a natural enzyme that has the ability to glue protein-containing foods together.
