Question

Question 1: Choose all correct regarding the human leukocyte antigen (HLA).

1. HLA is mediated by allelic variance

2. HLA (MHC) matching is crucial for transplant success

3. HLA loci give rise to MHC proteins on the cell surface

4. MHC and HLA are unrelated from a molecular standpoint

Question 2: Choose all true answers

Which of the following are true regarding HIV infection in humans.

1. HIV infects and kills the helper T cell which effectively eliminates the bodies ability to have an immune response

2. HIV is an RNA virus

3. HIV can be transmitted by simple touch (hand to hand)

4. HIV has a reverse transcriptase encoded in its genome and can therefore trasnscribe itself into DNA which then inserts into the hosts genome to replicated later by the hosts DNA polymerase
