Hey Mate!!!
Here is the answer
_______________
Stages of the cell cycle
_________________________
To divide, a cell must complete several important tasks: it must grow, copy its genetic material (DNA), and physically split into two daughter cells. Cells perform these tasks in an organized, predictable series of steps that make up the cell cycle. The cell cycle is a cycle, rather than a linear pathway, because at the end of each go-round, the two daughter cells can start the exact same process over again from the beginning.
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.
During interphase, the cell grows and makes a copy of its DNA.
During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
Interphase
• G_1 phase. During G_1 phase, also called the first gap phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks
• S phase. In S phase, the cell synthesizes a complete copy of the DNA in its nucleus. It also duplicates a microtubule-organizing structure called the centrosome.
• G_22 phase. During the second gap phase, or G_22phase, the cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for mitosis.

Heya jaani
The answer is here
The phases of the cell cycle are as follows
Each cell cycle is divided into two phases
A ) Interphase = 95% of cell cycle
B ) M- Phase = 5% pf cell cycle
( A ) Interphase
It is also called as resting phase of cell cycle because there is no chromosomal activity observed here .
It is divided into 3 phases
1 ) G1 phase = Longest phase of cell cycle
♢ Maximum gene occurrence anf cytoplasmic growth takes plac here .
♢ Each chromosome contain 1 chromatid and 1 DNA molecule .
2 ) S - Phase = It is concerned with DNA replication, DNA duplication and synthesis of DNA .
3) G2 Phase = Maximum cytoplasmic growth occurs here
♢ Concerned with the synthesis of proteins , required for spindle formation.
(B) M - Phase
It can be of two types
1 ) If it doesn't include spindle fibres then it is called as direct phase
2 ) And if it always include spindle formation then called as
Equational division i.e. Mitosis
Or
Reductional Division i.e. Meiosis
hope it helps
