DIFFERENTIATED CELL

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Although the genes found within stem cells are the same, stem cells differentiate into unique cell types (e.g., muscle cells, nerve cells, etc.) due to
A
meiotic division and fertilization.
B
random segregation and proliferation.
C
mutations in their genetic code.
D
different patterns in their gene expression.
Explanation: 

Detailed explanation-1: -Stem cells produce new cells by dividing. In the right conditions, these new cells can then continue to divide and differentiate into specialized cells. Stem cells can also divide to produce new stem cells to replace themselves.

Detailed explanation-2: -Stem cells are cells with the potential to form many of the different cell types found in the body. They can divide over and over again to produce new cells. As they divide, they can change into the other types of cells that make up the body.

Detailed explanation-3: -The cell types in a multicellular organism become different from one another because they synthesize and accumulate different sets of RNA and protein molecules. They generally do this without altering the sequence of their DNA.
