Question

What is responsible for telling cells how to behave

Answer 1

Scientists found that the cytoplasm of cells undergoing mitosis, if injected into cells at other stages of the cell cycle, could induce the non-dividing cells to start mitosis. This suggested that a chemical signal was present in the cytoplasm of dividing cells that was responsible for "telling" the cells that they should proceed into mitosis. By fractionating the cytoplasm into its components, scientists were able to isolate the signal that triggers mitosis.

Answer 2

Cellular differentiation and signaling

Step-by-step explanation:

Cells specialize in their functions due to the process of differentiation, transforming embryonic cells into new cells with specific morphology and physiology.

The behavior of cells for different functions is due to gene expressions and also thanks to receptors on the surface and inside the cell.

These receptors bind to signaling molecules, establishing communication between the nervous system and the others, ensuring the specificity of cells.
