QUESTION 1
Assuming there are colon tumor samples, one from a HNPCC patient, and the other from a FAP patient. One group shows
gross chromosomal abnormalities with chromosomal translocations, deletions, etc. The karyotype of the group, however,
looks mostly normal, and similar to noncancerous samples. Which group is expected to carry loss-of-function mutations in
MSH2 and MLH1 (DNA mismatch repair genes) as their primary driver mutations?
FAP that has grossly abnormal karyotype
HNPCC that has mostly normal karyotype
FAP that has mostly normal karyotype
