Question

What is interphase in mitosis?

Answer 1

Hint: Interphase and mitosis both are the phases of the cell cycle that perform their own function. They are both responsible for the division of the cell. One prepares the cell to divide while the other helps in the process of division.

Complete answer
The interphase is the phase of the cell cycle that is the longest and is responsible for the duplication of the DNA and growth of the cell. After this process, the cell will move towards the mitosis where the division starts, and then the alignment of the chromosomes occurs and results in the formation of the new daughter cells.

Additional information
-The cell division is also termed the cell cycle where the cells divide to form new daughter cells.
-The cell cycle is divided into two important phases: interphase, and mitotic (M) phase.
-The eukaryotic interphase four main phases, ${ G }_{ 1 }$, S phase, ${ G }_{ 2 }$, and mitotic phase.
-The interphase constitutes three phases ${ G }_{ 1 }$, S phase, and ${ G }_{ 2 }$.
-The ${ G }_{ 1 }$ phase is the first stage that helps in the formation of the mRNA and proteins helping in the process of meiosis.
-This phase is responsible for checking the preparation of the cell to undergo the cell cycle.
-The cell after this phase will enter the A phase where the DNA is replicated.
-The preparation of the cell is done by the ${ G }_{ 2 }$ phase before the cell enters the mitotic phase. This phase is called the growth phase.
-The mitotic phase is the phase where the cell starts to divide and results in the formation of two daughter cells. Here the chromosomes separate and are thus called the chromosome separation phase.
-Howard and Pelc were the first to describe the cell cycle.

Note:
A cell in interphase is different from a cell in the quiescent stage, this is also called a state of dormancy of the cells, but it is a is misleading term since a quiescent cell doesn’t halt metabolism, instead it is synthesizing proteins, transcription of DNA, engulfing extracellular material for food or defense, processing stimulus, etc. The cell is quiescent or dormant only with respect to cell division.
