Multiple Choice

Leukemia is cancer of the blood or bone marrow. There are many types of leukemia. One type of leukemia is caused by a mutation to chromosome 22. A piece of chromosome 22 and a piece of chromosome 9 exchange places, causing chromosome 22 to be shorter.

This mutation to chromosome 22 is ─

• a frameshift mutation because pieces of two chromosomes shifted location

• an inversion mutation because the chromosomes are no longer in the same order

• a translocation mutation because pieces of two chromosomes switched locations

• a substitution mutation because a piece of one chromosome is substituted for another
