The question that is given over here, it consists of two different parts.
00:05
We have to answer each and every part.
00:07
The first part of the question says that, what forms of the checkpoints do the normal cell take? and we must explain how do they control whether or not the cell dacons.
00:28
There are four different checkpoints.
00:32
The first is the restriction point.
00:35
The restriction point is also known as the g1 checkpoint.
00:54
This is a point in animal cell cycle at which the cell becomes committed to the cell cycle and this is determined by means of external factors and the signals.
01:18
The second one is the spindle checkpoint.
01:30
This is also known as the m checkpoint.
01:37
This prevents the separation of a duplicated point.
01:40
Chromosome until each chromosome is properly attached to the spindle apparatus.
01:45
One is recycling.
01:50
Any group of proteins that regulates the cell cycle by forming a complex with kinase, they are called as recitlons.
01:57
And at last, the g2 checkpoint...
