Question

When a typical restriction enzyme cuts a DNA molecule, the cuts are uneven, giving the DNA fragments single-stranded ends. These ends are useful in recombinant DNA work because
a. they enable a cell to recognize fragments produced by the enzyme.
b. they serve as starting points for DNA replication.
c. the fragments will bond to other fragments with complementary ends.
d. they enable researchers to use the fragments as molecular probes.

Accepted Answer

Hello everyone and welcome to today's video. So D. N. A. N. R. Characteristics of linear DNA molecules. The ends of D. N. A. In which one strand is longer than the other and the other strand has unpaid care basis are called. Which of these following options? Well you're going to see that when we cut D. N. A. We're going to be left with one of two options and we have them here. We can either have blunt and which is what we have here or we can have sticky ends which is what we have here. Now these sticky ends, we're going to have one strand that is longer than the other. And because of this it is not going to have nucleotides that is going to be binding to on the other strand because there's nothing here that it can bind to. This is exactly what the question is is describing. We have one strand that's longer and it has on pair basis. Because of this this type of end is going to be called sticky ins. Which is going to be answer choice. I really hope this video helped you and I hope to see you on the next one.
