Question

Why does a cell spend the most time in interphase?

Answer 1

Hint: The cell cycle is a sequence of events including cell growth and division that results in the formation of two new daughter cells. On their way to cell division, cells go through a series of carefully controlled and regulated stages of growth, DNA replication, and division that result in the formation of two identical (clone) cells. Interphase and mitotic phase are the two primary phases of the cell cycle. The cell expands and DNA is duplicated during interphase. During the mitotic phase, the cell divides and the replicated DNA and cytoplasmic contents are separated.

Complete answer:
The interval between mitotic divisions — \[G1\], S, and \[G2\] – is known as interphase. The cell expands during this phase, carrying out metabolic tasks necessary for the cell's regular maintenance and expansion. During this phase, cells produce proteins and expand to roughly double their original size. To summarise, during this phase, the cell grows, develops, prepares for cell division, replicates its chromosomes, and so on, and a cell spends the majority of its time in this stage. The cell then exits the interphase and enters the next phase to complete division.
The cell goes through typical growth processes while preparing for cell division during interphase. It is the longest phase of the cell cycle, with the cell spending over \[90\% \] of its time here. Many internal and external parameters must be satisfied for a cell to transition from interphase to mitotic phase.
\[G1\], S, and \[G2\] are the three stages of interphase.

Note:
Mitosis- The mitotic phase (sometimes referred to as the M phase) is a multistep process in which duplicated chromosomes are aligned, separated, and moved into two new, identical daughter cells. Karyokinesis, or nuclear division, is the first part of the mitotic phase. The physical separation of the cytoplasmic components into the two daughters, known as cytokinesis, is the second part of the mitotic process.
Karyokinesis- Karyokinesis, commonly known as mitosis, is the division of a cell and is separated into four phases: prophase, metaphase, anaphase, and telophase.
Cytokinesis- The physical separation of the cytoplasmic components into two daughter cells is accomplished during cytokinesis, the second main stage of the mitotic phase. The cell components must be apportioned and totally split into the two daughter cells before division is complete.
