Question

Why doesn't a skin cell make crystallin protein? Select all that apply. Select all that apply. Skin cells use different dna for their genes. Skin cells have the crystallin gene but do not express it. Skin cells do not need crystallin for their function. The crystallin gene is not present in skin cells?

Answer 1

Skin cells have the crystallin gene but do not express it.

Skin cells do not need crystallin for their function.

Step-by-step explanation:

I did the assignment on Master Biology (for the AP BIO course) lmk if it is wrong so I can remove my answer. :)

Answer 2

Answer;

-Skin cells do not need crystallin for their function.

-Skin cells have the crystallin gene but do not express it.

Explanation;

-The crystallin proteins are water-soluble structural proteins that occur in high concentration in the cytoplasm of eye lens fibre cells. It has also been identified in other places such as the heart, and in aggressive breast cancer tumors.

-The main function of crystallins at least in the lens of the eye is probably to increase the refractive index while not obstructing light. The skin cell does not make crystallin protein because the skin cells do not need crystallin for their function and also they have the crystallin gene but do not express it.
