Are your heart cells the same as your brain cells? Why or why not?(1 point) Responses Yes, during mitosis, the resulting daughter cells are identical which means that all cells in the body are the same. Yes, during mitosis, the resulting daughter cells are identical which means that all cells in the body are the same. No, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells. No, heart cells are stem cells that replicate and create brain cells, therefore they are two different types of cells. No, different sections of the cells' DNA are "tuned on" causing heart cells to have different characteristics from brain cells. No, different sections of the cells' DNA are "tuned on" causing heart cells to have different characteristics from brain cells. Yes, the heart cell and the brain cell have the same function, therefore they are identical. Yes, the heart cell and the brain cell have the same function, therefore they are identical.

Answer 1

No, different sections of the cells' DNA are "tuned on" causing heart cells to have different characteristics from brain cells.

Heart cells (cardiomyocytes) and brain cells (neurons) are specialized cell types that perform different functions in the body. Although they originate from the same genetic material, the way their DNA is expressed determines their characteristics and functions. This process is known as gene expression, which is influenced by various factors, resulting in the differentiation of cells into specific types. Hence, even though heart and brain cells share the same DNA, they are not identical due to differences in gene activation.
