You digest dna from the frog xenopus laevis with the enzyme noti that produces sticky dna ends. you can ligate your dna to:

Restriction enzymes such as Notl can be used to digest DNA from the frog Xenopus laevis that produce sticky ends. All restriction enzymes do not produce sticky ends. Some restriction enzyme might produce blunt ends.
The sticky ends produced by any restriction enzyme can be joined together with the help of ligase enzyme.

You can ligate your DNA to OTHER DNA MOLECULE WITH COMPLEMENTARY ENDS OR SAME DNA MOLECULE WITH THE HELP OF LIGASE ENZYME.
