The genetic information carried by a cell is passed on, generation after generation, with astonishing fidelity. However, genomes are still altered over evolutionary time scales, and even their overall size can change significantly. Which of the following genome-altering events has increased the size of the mammalian genome the most?
A) Transposition B) Point mutation C) Chromosomal deletion D) Chromosomal inversion E) Chromosomal translocation
