MCQ
More advancement in genetic engineering is due to
  • Restriction endonuclease
  • B
    Reverse transcription
  • C
    Protease
  • D
    Zymase

Answer

Correct option: A.
Restriction endonuclease
a
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.
