Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
During what phase of the cell cycle does the cell grow?
A
G1 phase
B
S phase
C
M phase
D
Cytokinesis
Explanation: 

Detailed explanation-1: -Interphase is a non-dividing phase that includes G1, S and G2 phases. During the G1 phase, the cell grows in size and synthesizes the cellular contents.

Detailed explanation-2: -Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth).

Detailed explanation-3: -G1 is followed by S phase (synthesis), during which DNA replication takes place. The completion of DNA synthesis is followed by the G2 phase (gap 2), during which cell growth continues and proteins are synthesized in preparation for mitosis.

Detailed explanation-4: -A cell grows during the G1 phase of the cell cycle. During this phase, more organelles are produced, a high amount of protein synthesis occurs and the volume of the cytoplasm increases. The cell continues to grow further in the G2 phase.

Detailed explanation-5: -G1 phase (Gap 1) – G1 phase is the phase of the cell between mitosis and initiation of replication of the genetic material of the cell. During this phase, the cell is metabolically active and continues to grow without replicating its DNA.
