Question

What is role of Dna ligase during Dna replication

Answer 1

HERE IS YOUR ANSWER.......

DNA ligase is an enzyme that repairs irregularities or breaks in the backbone of double-stranded DNA molecules.It has three general functions: It seals repairs in the
DNA , it seals recombination fragments, and it connects Okazaki fragments (small DNA fragments formed during the replication of double-stranded DNA ).
During DNA replication, the sytnthesis of a new strand of a DNA at a leading parent DNA strand is continous. However, it is discontinous at a lagging strand in the form of DNA segments. These DNA segments are known as Okazaki fragments. These fragments are later joined with the help of the enzymes DNA ligase.

Answer 2

Answer:

The enzyme is a useful tool in biotechnology since it can join two DNA strands.

Explanation:

• During cell division, DNA replication is aided by DNA ligase.
• One of these procedures is DNA replication, which duplicates DNA to guarantee equal genetic material transmission into daughter cells. Several enzymes aid in DNA replication.
• The double-stranded complex of DNA is "unzipped" during DNA replication to reveal two single strands, which are then utilized as templates to combine fresh monomers to create two daughter DNA molecules.
• An enzyme called DNA ligase is subsequently used to join the newly added monomers.
• The function of DNA ligase is crucial for the stability of the newly created DNA molecules as a result of DNA replication because it aids in the establishment of the phosphodiester bond that creates the DNA structure.
