Answer 1

Hello my friend! The correct answer is: C) They cut strands of DNA at specific sites.

Step-by-step explanation:

These enzymes are endonucleases, that is, inside (hence the endo-inside prefix) of DNA molecules, cutting them into well-defined locations.

These are enzymes always "poke" the DNA molecule at certain points, leading to the production of fragments containing sticky ends, which can bind to other ends of DNA molecules that have been cut with the same enzyme.
