Question

diff between m phase and interphase

Answer 1

The cell cycle alternates between M phase, or dividing phase, and Interphase, the nondividing phase:  

M phase, the shortest part of the cell cycle and the phase during which the cell divides, includes:  

1. Mitosis - division of the nucleus.  

2. Cytokinesis - division of the cytoplasm.  

Interphase, the nondividing phase, includes most of a cell's growth and metabolic activities.  

Is about 90% of the cell cycle.  

Is a period of intense biochemical activity during which the cell grows and copies its chromosomes in preparation for cell division.  

Consists of three periods:  

1. G1 phase - first growth phase. (G stands for "gap".)  

2. S phase - synthesis phase when DNA is synthesized as chromosomes are duplicated. (S stands for "synthesis".)  

3. G2 phase - second growth phase.

Answer 2

INTERPHASE

It the phase between two successive M phases.

It is the longest phase of the cell cycle.

Chromosomes are in the form of chromatin.

M PHASE

It is the phase during which actual cell division takes place.

It is the short phase of the cell cycle.

Chromosomes are thick and rod-like
