Your answer is After DNA replication, the cell leaves S phase and enters G2, when the cell prepares for mitosis or meiosis. At the G2 checkpoint, the cell checks two things. First, it checks DNA for any damage that might have occurred during replication. It also ensures all the proteins needed for cell division are present.

Answer:
1) intake of glucose molecules from the blood by specific transporters
2) high amount of glucose in the blood, sending signals toward the pancreas
3) binding of hormones with receptors on the liver
4) release of hormones from the receptors
5) synthesis of hormones by beta cells
Explanation:
During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells. The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
