Is a common test in the detection of testicular cancer.

Blood tests.

Explanation:

It is common to use blood tests to diagnose testicular tumors. Most testicular cancers produce substances that reach the blood and can be detected by blood tests. Such examination should always be performed at the beginning of patient care, and are very important in the diagnosis, quantification of the degree of disease impairment and serve as a parameter for follow-up after treatment. The major substances released into the blood indicating testicular cancer are alpha-fetoprotein (AFP) and human chorionic gonadotropin (GCH).

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.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!
