Which type of gene is most likely to be widely expressed in the body of someone who has superficial scrape?

A gene that stimulates and controls the production of white blood cells.

Explanation:

First, it is necessary to know that a gene is a sequence of DNA that has information for the formation of molecules necessary for the body. These molecules can be proteins, cells, enzymes, among other things that are needed at that very moment.

When a person on superficial scratches, the skin cells send a signal that it is necessary to defend the injured part from possible invaders that could harm the organism. At that moment, the genes come into action and are quickly expressed, not all of the organism's genes, but only those that contain information for the production and control of defense cells, the white blood cells, which will prevent invaders from using the scratches as entry into the body and cause damage.

Missing options in the question:

the gene that controls the production of stem cells

the gene that controls the production of skin cells

the gene that controls the production of red blood cells

the gene that controls the production of cardiac cells

Answer:

B. the gene that controls the production of skin cells

Explanation:

Superficial scrapes are the damages of upper skin layers which could occur due to accidents or sunburning. Upon damaging, body sheds the skin cells and then replaces with new cells. This process thus is governed by the expression of skin related genes.
