Question

All cells of the body originate from one cell called the zygote. This cell will give rise to all the cells of the body. Based on your knowledge of mitosis and cell differentiation, which of the following statements must be true?

A. All the cells of the body have different parts of the DNA from the original cell.
B. All the cells of the body have the same DNA, but use different parts of it.
C. All the cells of the body are exactly the same as the original zygote cell.
D. All the cells of the body have pieces of the original cell’s organelles

Answer 1

Answer: B

Explanation: How does a complex organism such as a human develop from a single cell—a fertilized egg—into the vast array of cell types such as nerve cells, muscle cells, and epithelial cells that characterize the adult? Throughout development and adulthood, the process of cellular differentiation leads cells to assume their final morphology and physiology. Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. All the cells of the body have the same DNA, but use different parts of it.

Answer 2

B

Step-by-step explanation:

Different cells use different parts of the DNA strand to perform their functions
