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.
Estimated Time
One 50-minute class period.
Key Terms
enhancer, regulation, regulatory switch, tissue-specific expression, transcription
