FIGURE 13.04 Temperature-Sensitive Fur Coloration

Some animals change colors in their extremities when body temperature is lowered in response to seasonal temperature change. The mutant gene for melanin is active at lower temperatures.

FIGURE 13.05 Nonsense Mutation

A mutation in the DNA has produced a new stop codon that causes premature termination of the protein. The shortened protein remains unfolded and is usually detected by the cell and degraded.
