Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Put the following in order:G2, G1, S, mitosis, cytokinesis.
A
G1, G2, S, Mitosis, cytokinesis
B
G1, S, G2, Mitosis, cytokinesis
C
G1, G2, S, cytokinesis, mitosis
D
G1, S, G2, cytokinesis, mitosis
Explanation: 

Detailed explanation-1: -The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase.

Detailed explanation-2: -The growth and division of a cell is orchestrated into a highly controlled and ordered process called the cell cycle. The cell cycle contains 4 stages; Gap 1 (G1) phase, synthesis (S) phase, gap 2 (G2) phase and mitosis (M) phase. For most human cells, a single cell cycle takes approximately 24 hours.

Detailed explanation-3: -These phases are prophase, prometaphase, metaphase, anaphase, and telophase. Cytokinesis is the final physical cell division that follows telophase, and is therefore sometimes considered a sixth phase of mitosis.

Detailed explanation-4: -Mitosis is conventionally divided into 5 phases, which include prophase, prometaphase, metaphase, anaphase and telophase and cytokinesis.

Detailed explanation-5: -cell cycle, the ordered sequence of events that occur in a cell in preparation for cell division. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
