Hello.
00:01
So let's identify as to what phase each event is happening in the cell cycle.
00:10
So we have here for letter a, the amount of nuclear dna in the cell doubles.
00:16
This happens during the s phase or the replication of the dna.
00:23
Next, for letter b, it says here that the nuclear envelope breaks into fragments.
00:28
This happens during the pro phase and that is on the m phase.
00:34
So our answer here is we have the m face.
00:38
Next for letter c, it states here that the sister chromatids separate from each other.
00:44
This happens during the anna phase.
00:46
So our answer here is we have the m phase.
00:51
Next, for letter d, it says here that the cells will never divide again and likely to be arrested.
01:00
So this face is the g0 phase, but since the g0 phase is not in the option, therefore our answer here is none of the phases.
01:14
So none of the faces.
01:21
Next for letter e, the primary cell wall of the plant cell forms.
01:29
This happens during the cytokinesis of the plant cell.
01:33
And that happens during the m phase.
01:36
So our answer here is we have the m face.
01:39
Next, we have here letter f.
01:42
It says that the chromosomes are present as diffuse extended chromatines.
01:47
So chromatines are present in g1 phase.
01:54
It is also present in the s phase...
