Q. Consider the following two statements and select the correct option.
Statement I: Each restriction endonuclease functions by ‘inspecting’ the length of a $DNA$ sequence.
Statement II : Once it finds its specific recognition sequence, it will bind to the $DNA$ and cut hydrogen bonds.

Biotechnology : Principles and Processes

Solution:

• Each restriction endonuclease functions by ‘inspecting’ the length of a DNA sequence.
• Once it finds its specific recognition sequence, it will bind to the DNA and cut each of the two strands of the double helix at specific points in their sugar phosphate backbones.
