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
