|
|
DNA ligase
|
|
|
restriction enzyme
|
|
|
reverse transcriptase

Explanation:
Detailed explanation-1: -Blunt-ended fragments can be joined to each other by DNA ligase.
Detailed explanation-2: -Answer and Explanation: Technically, restriction enzymes create DNA fragments with sticky ends.
Detailed explanation-3: -Blunt ends are also called non-cohesive ends, since there is no unpaired DNA strand fleeting at the end of DNA. The sticky ends, a.k.a. cohesive ends, have unpaired DNA nucleotides on either 5’-or 3’-strand, which are known as overhangs.
