Restriction endonucleases are enzymes which:

  1. A
    Remove nucleotides from the ends of the molecule.
  2. B
    Make cuts at specific positions within the molecule.
  3. C
    Recognize a specific nucleotide sequence for binding of ligase.
  4. D
    Restrict the action of the enzyme polymerase.

Solution & Step-by-step Explanation

Restriction endonucleases (molecular scissors) recognize specific short sequences of bases (palindromes) and cut the at specific positions within that sequence. Exonucleases are the ones that remove nucleotides from the ends.
