Explanation:
Endonucleases are a type of restriction enzyme that cuts the DNA at a specified location. It is widely used to clip the sequence in order to obtain DNA fragments with sticky ends. Sticky ends are single-stranded DNA segments that can establish hydrogen bonds with adjacent cut DNA segments. The enzyme ligase later joins these ends. Exonuclease is a restriction enzyme that removes nucleotides from the 5' and 3' ends of DNA strands.
