Figure 5.22: Mutations can arise in DNA through deletion, duplication, inversion, insertion,
and translocation within the chromosome. A deletion is when a segment of DNA is lost from
the chromosome. A duplication is when a segment is repeated. In an inversion, the segment
of DNA is flipped and then re-annealed. An insertion or translocation can cause DNA from
one chromosome to be added onto another, unrelated chromosome. ( 18 )
