Hello, so let's answer now the problem.
00:02
So here in the problem we have a cell that is undergoing a cell division, and specifically this cell division is what we call meiosis, since we see here that the homologous chromosomes are going to be separated in this division.
00:17
So first, these two cells that you are seeing is what we call a homologous chromosome.
00:25
So it is a homologous pair.
00:30
So homologous chromosome.
00:39
And here we see that the point of attachment between the two homologous chromosomes, wherein there is this genetic exchange between two non -sister chromatids, is what we call the chayasma.
00:54
So this is the chayasma.
00:57
So the part of the two homologous chromosomes wherein the exchange of the genetic material happens is the chayasma.
01:05
And here we see that this portion is what we call the centromere.
01:16
The centromere is the point of attachment between two sister chromatids.
01:22
So what holds the two sister chromatids in a chromosome is the centromere.
01:28
And also at the side of the centromere, we can see the kinetocor, wherein in this area, the microtubules will attach.
01:37
To the chromosome so the microtubules will attach to the chromosome in the kinetocor and here this line is what we call the microtubules okay the microtubules and the source of microtubules to separate the chromosomes are the centrioles so this is the centrioles okay centrials and here since the chromosomes or the homologous chromosomes are lining in the middle.
02:18
This is what we call the metaphaease plate.
02:20
The middle portion is what we call the metaphase plate...
