Question
How Cells Are Used in the Body Quick Check
Are your heart cells the same as your brain cells? Why or why not?
A. Yes, the heart cell and the brain cell have the same function, therefore they are identical.
B. No, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells.
C. Yes, during mitosis, the resulting daughter cells are identical, which means that all cells in the body are the same.
D. No, different sections of the cells' DNA are "turned on," causing heart cells to have different characteristics from brain cells.

The correct answer is:
**D. No, different sections of the cells' DNA are "turned on," causing heart cells to have different characteristics from brain cells.**
Heart cells and brain cells have different functions and characteristics because they express different genes, even though they originate from the same genetic material in the zygote. This process is known as gene regulation, and it determines the specific traits and functions of each cell type.
