Cells such as neurons, which rarely if ever divide, can be explained as __________.
A) being in the G0 phase of the cell cycle
B) unable to activate apoptosis
C) being in the G1 phase of the cell cycle
D) having no active cell cycle
I'm pretty sure it's A
neurons (nerve cells) and red blood cells also cardiac cells, brain cells, corneal cells and skeletal muscle cells are stuck in the GO phase, and very seldom divide.
I am pretty sure you are right.
thank you!
You are correct! Cells such as neurons, which rarely if ever divide, can be explained as being in the G0 phase of the cell cycle. In this phase, cells temporarily or permanently exit the cell cycle and enter a state of quiescence or non-dividing. Neurons are one example of cells that reach this state and remain in it for most of their lifespan. This is in contrast to other cells in the body that actively go through cell division. So, option A) being in the G0 phase of the cell cycle is the correct explanation.
You're on the right track! The correct answer is A) being in the G0 phase of the cell cycle.
The cell cycle is the series of events that a cell goes through as it grows and divides. It consists of several phases, including the G1 phase, S phase, G2 phase, and M phase (mitosis phase).
Cells in the G0 phase are in a resting or non-dividing state. They have exited the cell cycle and are not actively preparing to divide. This phase is commonly observed in nerve cells (neurons) and other specialized cells that have reached their final functional state, as they no longer need to replicate or divide.
Neurons are highly differentiated cells and have a limited ability to regenerate or replace themselves. Therefore, they remain in the G0 phase for most of their lifespan, carrying out their functions without undergoing cell division.
So, in summary, neurons and other non-dividing cells can be explained as being in the G0 phase of the cell cycle.
