THE CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is NOT a phase in the cell cycle process?
A
G1
B
G2
C
M
D
all of these are part of the cell cycle
Explanation: 

Detailed explanation-1: -Solution : interphase in a cell cycle has three stages ‘-G (1 ), S‘ and ‘G (2)‘ M-phase is not a part of interphase.

Detailed explanation-2: -M-phase is not a part of interphase.

Detailed explanation-3: -In eukaryotes, the cell cycle consists of four discrete phases: G1, S, G2, and M. The S or synthesis phase is when DNA replication occurs, and the M or mitosis phase is when the cell actually divides. The other two phases-G1 and G2, the so-called gap phases-are less dramatic but equally important.

Detailed explanation-4: -These phases are prophase, prometaphase, metaphase, anaphase, and telophase.

Detailed explanation-5: -The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.
