Description

This two-slide tutorial describes how genetic switches, regulatory elements in DNA, control gene expression.

Genetic switches can turn genes on and off in different tissues. In this Click & Learn, students explore two examples: the regulation of the Pitx1 gene in stickleback fish, which affects body morphology, and the regulation of the “paintbrush” gene in Drosophila fruit flies, which affects wing pigmentation.
