Restriction endonuclease
B
Reverse transcription
C
Protease
D
Zymase
Solution
Endonucleases are enzymes that produce internal cuts called cleavage $DNA$ molecule. $A$ class of endonucleases cleavage $DNA$ only within or near those sites which have specific base sequences, such endonucleases are known as restriction endonucleases and sites recognized by them are called recognition sites. Restriction endonucleases have major role in genetic engineering
