Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In what part of the cell cycle do cells spend the majority of their time?
A
S-Phase
B
Cytokinesis
C
Interphase
D
Nuclear Division
Explanation: 

Detailed explanation-1: -A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.

Detailed explanation-2: -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-3: -A cell spends the longest in Interphase due to the following reasons: Cell growth takes place during this period. DNA synthesis takes place which is in preparation for pre-mitotic division. Replication of chromosomes takes place.

Detailed explanation-4: -Growth Phase 1 (G1): during this phase, the cell grows rapidly, while performing routine metabolic processes. It also makes proteins needed for DNA replication and copies some of its organelles in preparation for cell division. A cell typically spends most of its life in this phase.
