Professor PC Thomas Classes · Answer

(b) : Exonucleases remove nucleotides from the terminal ends (either 5' or 3') of DNA of one strand of duplex. Endonucleases make cut at specific position within the DNA. DNA ligases are known as joining or sealing enzymes. Ligases form phosphodiester bonds between adjacent nucleosides and covalently link two individual fragments of DNA. Hind II is restriction endonuclease. It cuts the DNA and produces blunt ends.
