Are your heart cells the same as your brain cells? Why or why not?

Question

A: no, different sections of the cells DNA are " turned on" causing heart cells to have different characteristics from brain cells

B: no, heart cells are stern 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: yes, the heart cell and the brain cell have the same function, therefore they are identical

Answer 1

The correct answer is A: no, different sections of the cells' DNA are "turned on," causing heart cells to have different characteristics from brain cells.

Explanation: While all cells in an organism have the same DNA, different types of cells (like heart cells and brain cells) express different sets of genes. This differential gene expression leads to the unique structures and functions of different cell types. Heart cells (cardiomyocytes) are specialized for contraction and pumping blood, while brain cells (neurons and glial cells) have functions related to signaling and support in the nervous system.
