Which of the following enzymes catalyse the removal of nucleotides from the ends of DNA?
1. endonuclease
2. exonuclease
3. DNA ligase
4. Hind - Il
(i) Exonucleases remove nucleotides from the ends of the DNA.
(ii) Endonucleases make cuts at specific positions within the DNA.
DNA ligase is a sealing enzymes (also called as genetic gum), which is responsible for joining of two individual fragments of DNA, whereas Hind Il is first discovered restriction endonuclease enzyme.
