Mutations
Mutations are changes in the genetic code. They can be created when copying errors occur during DNA replication. Sometimes, they are caused by environmental damage, like UV light from the sun or pollutants in the air or water. Other times, they are caused by viruses, like HPV, or human papillomavirus. This is a virus that damages the DNA in the cervix of women, causing the cells to reproduce too quickly and form a cancerous tumor. You have probably seen the Gardasil vaccine commercials on TV in which a teenaged boy or girl asks their parents, "Mom...Dad...did you know?"

Original - horse shoer
Original - horse shoer
Insertion - shower
Insertion - shower
('w' was inserted, thus shoer becomes shower)
Deletion - shoe
Deletion - shoe
('r' was deleted, thus shoer becomes shoe)
Inversion - shore
Inversion - shore
(the 'e' and 'r' were inverted, or changed positions, thus shoer becomes shore)
Substitution - sheer
Substitution - sheer
(the 'o' was substituted for an 'e,' thus shoer becomes sheer)
Even a tiny change in the genetic code can cause big changes in an organism. You may have heard of one or more of the following diseases, caused by a single incorrect nitrogen base (A, T, C, or G).
