In biotechnology, sticky ends are select one:
a. dna fragments cleaved by a restriction enzyme so that both strands are the same length.
b. dna fragments that carry a higher charge than normal after they have been cleaved by restriction enzymes.
c. dna fragments cleaved by a restriction enzyme so that one strand is longer than the other.
d. dna fragments that attract a carbohydrate molecule to one end after being cleaved by a restriction enzyme.

Option (a).

Explanation:

Restriction enzymes are also known as molecular scissors that are used to cleave the specific DNA strands. Two main types of restriction enzyme are restriction endonuclease and restriction exonuclease.

The restriction enzyme has the ability to cleave the DNA fragment at or near the specific sites. The ends generated by the restriction enzyme has the same length of both the strands.

Thus, the correct answer is option (b).

the second type of galaxy is called a barred spiral, which has a thing called a bar straddling the nucleus
