Question

Select the correct answer.

Skin and nerve cells have different appearances and characteristics from each other, although they contain the same DNA. Why?

A.
The DNA in nerve cells undergoes mutations making them different from the DNA in skin cells.
B.
The genes in skin cells are transcribed but not translated as genes of nerve cells.
C.
The genes expressed in skin cells may not be expressed in nerve cells and vice versa.

Answer 1

C. The genes expressed in skin cells may not be expressed in nerve cells and vice versa.

Although all cells in an organism contain the same DNA, the expression of genes varies between cell types. Different cells express different sets of genes depending on their function and location within the body. This differential gene expression leads to the development of specialized cells with distinct characteristics and functions. In the case of skin and nerve cells, they have different appearances and characteristics because they express different sets of genes, even though they contain the same DNA.

Answer 2

C

Step-by-step explanation:

The genes expressed in skin cells may not be expressed in nerve cells and vice versa.
