A 48-year-old man who has been HIV positive for 6 years has just learned that he has been diagnosed with Kaposi sarcoma (KS). Which fact most accurately conveys an aspect of his diagnosis?

Hello! I figured that your question was lacking its options so I went to look for them online. Here they are:

A) He is likely to have lesions on his skin, mouth or GI tract.

B) Heterosexual contact most likely underlies his HIV and subsequent KS.

C) An opportunistic Epstein-Barr virus underlies the man's KS.

D) Intense pain was probably his first manifestation of KS

The correct answer is: A) He is likely to have lesions on his skin, mouth or GI tract.

Explanation:

Kaposi's sarcoma is a type of opportunistic infection (meaning that is much more likely to occur in immunocompromised people) that causes a tumor on the skin that presents itself with purplish spots on the neck and head, and can also appear in the gastrointestinal tract and the lungs.

Men who engage sexually with other men are at a higher risk of HIV and SK than men who do so with women.

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.
