Title: Genetic Corn
Description: An ear of corn, the kernels are varied in color. Researchers suggest that retroviruses have additional stretches of DNA that act as switches, turning on genes when inserted next to them in the cell's chromosomes. Similar activation of genes causes the variation in pigmentation of these corn kernels.
