विस्तृत व्याख्या:

Restriction Endonucleases and Recognition Sequences (प्रतिबंधन स्थल):

• Restriction endonucleases (molecular scissors) cleave double-stranded DNA at or near specific nucleotide sequences.
• The specific 4 to 8 base-pair DNA sequence recognized and bound by a restriction endonuclease is officially known as the Recognition sequence or Restriction site (पहचान अनुक्रम या प्रतिबंधन स्थल).
• In Type II restriction enzymes (such as EcoRI, recognizing $5'\text{-GAATTC-}3'$), these sites are typically palindromic sequences with two-fold rotational symmetry.

Correct Answer: Option 3 (Recognition sequence or restriction site).
