I think the correct answer from the choices listed above is option A. Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA because the genes expressed in inskin cells may not be expressed in nerve cells and vise versa.

Answer:

The correct answer is A. the genes expressed in skin cells may not be expressed in nerve cells and vise versa.

Explanation:

Every cell in the body contains the same set of genes in their chromosomes but only some fraction of its gene expresses which allows the different cells to appear and function differently in their environment.

Therefore every cell makes different proteins according to the job that cell performs like in RBC genes are expressed to synthesize the hemoglobin proteins but other cells do not produce this protein because genes for hemoglobin is not expressed in them.

Therefore the right answer is A. the genes expressed in skin cells may not be expressed in nerve cells and vise Versa.
