So, in this question, we will see a key concept.
00:05
So, we have different phases in the cell cycle.
00:09
We have g1 phase, s phase, g2 phase, m phase, m phase and then g0 phase.
00:24
So, g1 phase, in this phase, it determines whether the cell will commit the cell division or it will leave the cell cycle.
00:37
In this phase, the required protein, the required proteins and mrna, they are produced.
00:51
They are produced for the s phase.
00:56
So, now, if the gene regulatory protein, the gene regulatory protein of e2f family, it becomes, it becomes unrestrained and increase the g1 or you can say s cycle gene extensions.
01:25
So, it leads to the tumor.
01:28
The cell cycle got uncontrolled and this will lead to tumor.
01:31
Now, if we talk about the s phase, in s phase what happens, the dna packed into the chromosome.
01:43
The dna is packed into the chromosome and is replicated to provide the daughter cell, daughter cell in the same genetic metal...
