Correct Answer: D
Rationale: LMP and TAP genes are involved in antigen processing for MHC class I presentation.

Because of a lack of genetic recombination in the MHC, blocks of alleles (haplotypes) are inherited together, and they are identical in families. Which of the following is the likely result of this?
Correct Answer: A
Rationale: Identical HLA haplotypes in families simplify tissue transplantation due to matched alleles.
