Question

Which cell in the human body have the gene that encodes rhodopsin? A) only cells of the retina in the eye have the gene for it B) Only cells of the germline have the gene for it C) All nucleated types have the gene for rhodopsin D) Only cells of the germline and cells of the retina have the gene.

Answer 1

Ans. -

Rhodopsin is a type of pigment, which is necessary for normal vision, particularly in low-light conditions. Rhodopsin is found in specialised cells called rods which are located at the retina in the light-sensitive area of the eye. Rodopsin, also called visual purple , pigment-containing sensory protein that converts light into an electrical signal. it is required for vision in dim light and is located in the retina of the eye—specifically, within the tightly packed disks that make up the outer segment of the retina’s photoreceptive rod cells, which are specially adapted for vision under low-light conditions.

Germline cells that form the egg, sperm and the fertilised egg, as well as the fertilised egg's future sperm or egg cells.

So, correct option is d
