Question

During the process of genetic engineering ligase is used during
a)rDNA formation
b)isolation of gene
c)isolation DNA
d)incorporation of rDNA into host​

Answer 1

Answer:

Answer is a

Explanation:

During normal DNA replication, DNA ligase catalyzes the end-to-end joining (ligation) of short fragments of DNA, called Okazaki fragments. For purposes of DNA cloning, purified DNA ligase is given to covalently join the ends of a restriction fragment and vector DNA that have complementary ends.

Answer 2

Answer:Here's your answer

Explanation:

If restriction enzymes are like molecular scissors, then DNA ligase is like molecular glue. Scientists can use restriction enzymes to generate DNA fragments and DNA ligase to glue those fragments together.Then, we can cut a DNA plasmid with the same restriction enzymes.
