1.	Retinitis pigmentosa is an inherited disorder caused due to mutation in the gene that encodes for __________________(a) G-proteins(b) Arrestin(c) Rhodopsin(d) G-protein receptor kinaseI had been asked this question in an interview for internship.My question comes from Cell Signaling and Signal Transduction in section Cell Signaling and Signal Transduction of Cell Biology
Answer» Right answer is (c) Rhodopsin The best I can explain: Retinitis pigmentosa (RP) is an inherited disorder CHARACTERIZED by progressive degeneration of the retina and EVENTUAL blindness. The DISEASE is caused due to mutation in a gene that encodes the visual PIGMENT of rods – rhodopsin.
