Question

Quizplus · Accepted Answer

A chromosomal translocation involves two different chromosomes breaking and the broken ends joining together, resulting in a rearrangement of genetic material between them. A single chromosome breaking in two locations would result in a deletion or duplication, but not a translocation. The presence of a transposon or a mutation in the DNA may contribute to instability and increase the likelihood of a translocation, but they are not necessary or sufficient events to cause it. The crucial step in a translocation is the correct pairing and fusion of the broken ends, which can have different outcomes depending on the orientation and location of the breakpoints.
