An egg and sperm cell combine to create a fertilized egg. After multiple cell divisions, the fertilized egg results in many different types of cells, such as: blood cells, bone cells, gland cells, and nerve cells.
The specialized cells in the image develop during cell differentiation. How does the cell cycle ensure cells are able to specialize?
A.
It adds new DNA to the cells that code for specific functions.
B.
It copies the DNA that provides the instructions for specialization.
C.
It splits up the DNA into different cell types during cellular division.
D.
It combines the DNA from the sperm and the egg cells to create cells with unique functions.

The correct answer is:
B. It copies the DNA that provides the instructions for specialization.
During the cell cycle, each time a cell divides, it replicates its DNA, which contains the instructions necessary for the cell's specialization and function. This process allows for the proper distribution of the genetic material needed for various types of specialized cells to develop.
