Think of it as … WebThe most common of these rearrangements is an inversion of a region of chromosome 16 (written as inv(16)). An inversion involves breakage of the chromosome in two places; the resulting piece of DNA is reversed and reinserted into the chromosome. Less commonly, a translocation occurs between the two copies of chromosome 16 (written as t(16;16)).
