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.

1. true.2. true.3. true.4. false.5. true.the concept of darwin's theory of evolution involves the idea that there are limited resources in a given living environment and that the organisms which live within have variations in their genetic make up due to random mating. the ones with beneficial genetic variations can express certain traits which give them an upper hand in surviving and reproducing in the said environment compared to ones who may have a more disadvantageous variation in traits. over time, the organisms with an upper hand will survive and reproduce more frequently and pass on their beneficial genes while the others die. the result is evolution, where we observe (usually, but not always) eventually, phenotypic distinct changes.
