Question

Cell division is regulated by: signals that indicate that DNA has been replicated. signals about the nutritional status of the cell. All of these choices are correct. growth factor signals. signals that indicate that the cell has reached a sufficient size.

Answer 1

Answer:

The correct answer will be option-All of these are correct

Explanation:

Cell division is highly influenced by the external and internal factors which decide whether the cell division will move forward or not.

The cell division cycle is checked at various stages called checkpoints which checks if the condition is favorable or not.  There are three checkpoints namely at G₁/S, G₂/M and between metaphase and anaphase.

The G₁ checkpoint checks for the DNA damage, size of the cell, Nutrient availability to divide while G₂ checks if the DNA is replicated accurately.

Thus, All of these are correct is the correct answer.
