What is the name given to all of the known materials used for comparison in this experiment

Answer;

-Controls

Explanation;

A control is something that is used as a standard of comparison for checking the results of an experiment. A control is important for an experiment because it allows the experiment to minimize the changes in all other variables except the one being tested.

There will frequently be two groups under observation in an experiment, the experimental group, and the control group. The control group is used to establish a baseline that the behavior of the experimental group can be compared to.

-Without an experimental control group, it is difficult to determine the effects of the independent variable on the dependent variable in an experiment.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
