CELL CYCLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What stages of the cell cycle make up interphase?
A
Prophase, Metaphase, and Telophase
B
Gap 1, Synthesis, and Cytokinesis
C
Gap 1, Gap 2, and Synthesis
D
Anaphase, Prophase, and Cytokinesis
Explanation: 

Detailed explanation-1: -The interphase is the period when the cell is in a non-dividing state and this can be in different stages: the first gap (G1) between the last mitosis and the S phase (phase of DNA synthesis) and the second gap (G2) between the completion of the S phase and the next mitosis (M).

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: -There are three stages of interphase: G1 (first gap), S (synthesis of new DNA ), and G2 (second gap). Cells spend most of their lives in interphase, specifically in the S phase where genetic material must be copied. The cell grows and carries out biochemical functions, such as protein synthesis, in the G1 phase.

Detailed explanation-4: -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-5: -G2 phase (Gap 2)-The Cell “double checks” the duplicated chromosomes for error, making any needed repair.
