Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following correctly describes cell that are in the G0 phase?
A
Mature nerve and muscle cells are unable to divide and are permanently in G0.
B
Many cells enter G0 when they reach the checkpoint during the M phase.
C
Cells in G0 are growing and preparing for cell division.
D
DNA replication occurs during G0.
Explanation: 

Detailed explanation-1: -Cells in the G0 stage remain metabolically active but no longer divide.

Detailed explanation-2: -So, the correct option is ‘Neither mitogens nor energy-rich compounds are present. ‘

Detailed explanation-3: -Differentiated bone Of the four major types of bone cells, osteocytes are the most common and also exist in a terminal G0 phase.

Detailed explanation-4: -Other cells that never or rarely divide, such as mature cardiac muscle and nerve cells, remain in G0 permanently (Figure). Cells that are not actively preparing to divide enter an alternate phase called G0.
