Restriction enzymes that are used in the construction of recombinant $DNA$ are endonucleases which cut the $DNA$ at 'specific-recognition sequence'. What would be the disadvantage if they do not cut the $DNA$ at specific-recognition sequence?

  • A
    The $DNA$ fragments would be too large to be cloned.
  • B
    The $DNA$ fragments would not have complementary sticky ends,making recombinant $DNA$ construction impossible.
  • C
    The $DNA$ would be degraded completely by the enzymes.
  • D
    The $DNA$ would not be able to replicate inside the host cell.
