Answer 2

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
