Question

If a specialised cell no longer divides, it is generally locked in which stage of the cell cycle?

• A. M
• B. S
• C. $G_2$
• D. $G_1$

Answer 1

The correct option is D $G_1$

• A cell in any multicellular organism has a specific number of times where it can undergo cell cycle where it divides to form daughter cells.
• The G1 phase of the interphase of cell cycle is the stage between the M phase and the S phase of the cell cycle.
• M phase is where the division of the cell takes place and S phase is where the DNA for the cell division is replicated.
• When a cell has undergone enough number of cell division and now is mature enough or does not require to divide it enters the $G_1$ or $G_0$ phase where it will continue to function as a normal cell but will not be required to go under cell division.
• For example the region of maturation or region of differentiation in the root tip of a plant.
  
• Therefore the correct answer is option 'G1'.
