The correct answer is A. Experimental group

Explanation:

In experiments, the experimental group refers to the group of subjects that receives special treatment or in which the scientist or researcher intervenes. This is the opposite of a control group that does not receive treatment and therefore, it is used as a reference to measure the effect of the treatment.

This implies, in the experiment presented Group A is the control group as they do not have special treatment because they sleep normally and Group B is the experimental group as the researcher modifies their sleep time and reduces it two hours which means in this group there is a treatment or intervention.

Where would the enzyme topoisomerase attach during dna replication?
babunello [35]
When DNA replication occurs, the DNA strand is being unwound, causing the DNA to be overwound tightly past the replication fork.
For example, If you have ever wrapped two strings around each other and then tried to pull part the middle of the string while holding the ends tight, the rest of the string past the place you're pulling the string apart becomes very tight and strained.

Topoisomerase is an enzyme that binds to the DNA and helps release some of that strain by unwinding the DNA past the replication fork.

That means the correct box is the leftmost one. Hope this helps:)
