Isabella liked to sunbathe. However, after she learned that ultraviolet rays are a cause of environmental mutations, she decided to stop sunbathing. Another kind of mutation is genetic, and it is caused by small changes in an organism's DNA. A change in a base pair is a mutation. This can cause the

A. DNA sequence
B. deletion
C. addition
D. sex-linked
E. substitution
F. expression
