Hint: A cell is the smallest part of any organism that gives it structure and performs various functions. Every cell is microscopic and surrounded by a membrane, it is made up of a nucleus as well as cytoplasm. The cell cycle is a sequence of events that are enclosed in parent cell division and then the further development into two individual daughter cells.
Complete answer:
In short, the cell is in interphase as it is replicating its DNA information in preparation for mitosis. After the final stage of mitosis cytokinesis occurs, which marks the end of the cell cycle.
Remember that a cell must perform several tasks in order to divide:
It must initially grow over time, then it should copy the genetic material (that is the DNA), and continue to physically break into two daughter cells. So basically, the cell cycle is an ordered and predictable sequence of steps in which cells perform the required tasks.
The complete cycle in brief is:
- During the interphase, the cell becomes bigger and divides and duplicates the DNA.
- Then as the mitotic (M) process goes on, the cell divides its cytoplasm and forms two sets of DNA, resulting in the formation of new cells, specifically two in number.
Now starting with the interphase:
It is said that the cell grows bigger physically, then it moves on to copy the organelles of the cell, to then create the molecule’s building blocks that it might need in later steps during the ‘first gap phase’. The cell makes a full copy of DNA in its nucleus during the ‘S process’. It also duplicates the centrosome (a microtubule-organizing structure). After that, during the ‘M process’, centrosomes assist in the separation of DNA. In the ‘second gap phase’ the cell continues to expand, producing proteins and organelles as well as reorganizing its contents in preparation for mitosis.
Then for mitosis:
We can say that the cell's nuclear DNA changes into recognizable or individual chromosomes during mitosis, and the mitotic spindle, a specialized structure consisting of microtubules, pulls them apart. In order of sequence starting with prophase, moving on with metaphase, going into the anaphase, and ending in telophase, the four stages of mitosis will take place.
After that the cytokinesis comes:
The cytoplasm of the cell is split in two during cytokinesis, resulting in the formation of two new cells. With a little overlap, cytokinesis normally starts just as mitosis is ending. Take note that cytokinesis occurs in animal and plant cells in various ways. The contractile cytokinesis comes into play as a band of cytoskeletal fibers also known to be the contractile ring contracts towards the inside and separates the cell in half in animals.
Plants have a solid cell wall that surrounds them and a high internal pressure. Plant cells divide in half as a result of this by constructing a new structure in the center of the cell that is made up of plasma membrane and cell wall components delivered in vesicles and divides the cell in half.
Note: A cell's primary function is to coordinate. Cells are used to store a number of items, and each cell has its own set of functions. Take for example blood cells, they circulate across the body. Other cells, like muscle cells, are bound to one another and remain stationary. Skin cells, for example, divide and replicate rapidly. Nerve cells do not divide or replicate unless certain conditions are met.
