In a mitotic cycle, the correct sequence of phases is:

Options

  1. AS , G 1 , G 2 , M
  2. BG 1 , S , G 2 , M
  3. CM , G 1 , G 2 , S
  4. DG 1 , G 2 , S , M

Correct answer

B. G 1 , S , G 2 , M

Step-by-step solution

The cell cycle is divided into two basic phases: a. Interphase: The phase between subsequent cell divisions is called the interphase. The interphase lasts for more than 95 % of the cell cycle. The interphase is further divided into three stages, i.e. G 1 ,   S   and   G 2 . b. M Phase (Mitotic phase): The actual cell division takes place in the M - phase. The M - phase lasts for less than 5 % of the cell cycle.
