First discovered restriction endonuclease that always cuts DNA molecule at a particular point by recognising a specific sequence of six base pairs is:

Options

  1. AEcoR I
  2. BAdenosine deaminase
  3. CThermostable DNA polymerase
  4. DHind II

Correct answer

D. Hind II

Step-by-step solution

The first restriction endonuclease Hind II always cuts DNA molecule at a particular point by recognising a specific sequence of six base pairs. This specific base sequence is known as the recognition sequence for Hind II .
