Cholera is caused by a comma-shaped bacterium, Vibrio cholerae, which is ingested in contaminated water and food. The bacteria multiply enormously in the intestine, where epithelial cells allow fluid to leak into the
intestine with intense diarrhoea as a result. Cholera is endemic in India and other parts of the third world.
4. Scientists have found that the mutation affects the same G-protein involved in cholera. This G-protein gets active continuously.
5. Skin cells, this causes darker pigment. G-protein involved in cholera. This G-protein gets active continuously.
6. Bone cells, it causes weakness and fractures.
