What is the job of the DNA ligase?

Answer 1

It joins Okazaki fragments

Answer 2

DNA ligase plays a very important role in rDNA technology.It seals the single strand nicks in the double stranded DNA.It forms a phosphodiester bond between the two nucleotide.Based on the type of energy they use during ligation DNA ligase are of two types:

1.E.coli DNA ligase(which uses NAD as a source of energy) and

2.T4 DNA ligase(which uses ATP as a source if energy)

Answer 3

DNA ligase joins join DNA strands by restoring/creating phosphodiester bonds. This is useful for recombination, replication and repair.
The ligase enzyme glues the pieces of DNA together. It's normal function is repairing double strand breaks in DNA molecules.

Answer 4

When you digest a plasmid, for instance you cut it at certain base pairs. Ligase is the enzyme that can " paste these cut ends together into whole plasmids with differing genetic complements. It is also useful for other forms of DNA.

Answer 5

DNA ligase is an enzyme which seals gaps in the sugar - phosphate backbone of DNA molecules.

This is necessary in the replication of DNA as the lagging strand is synthesised in short fragments by DNA polymerase. The gaps between the fragments are then sealed by DNA ligase.

DNA ligase is also very important in genetic engineering. When a plasmid (circular strand of DNA) is cut open and an extra section of DNA inserted, it is DNA ligase which seals the two DNA molecules together.

Answer 6

DNA ligase repairs the damage created with restriction enzyme. DNA ligase seals the DNA together. At that point, you officially have a recombinant DNA organism.

Answer 7

Ligase joins together the Okazaki fragments into a continuous strand of DNA.

Answer 8

it ties chunks of DNA together. Apex

Answer 9

It joins Okazaki fragments
