This pair will eventually move to one pole and the other chromatid will move to the other pole. The movement of chromatids is a major feature of mitosis. BT102 PAST PAPERS

Chromosome movements are highly regulated
The next three stages of mitosis – prometaphase, metaphase and anaphase – are the stages in which chromosomes actually move. In such cases,
The centromere and the former female chromatids, which keep the two chromatids apart, move away from each other.

In promethazine, the
chromosomes move towards the poles, but this
The movement was hindered by two factors:
an attractive force pushes the chromosomes away from the poles

The two chromatids are still attached to the cochlear centromere.

The daughter is defined as the chromosome.
What triggers this highly constant mass displacement
Clearly two things seem to move the chromosomes. First, kinetogens are proteins that act as “molecules”.

chromosomes for them. This summary is in the account
About 25 percent movement.
During Anabas, the spiral pushes the poles, doubling the distance between them. Distance
grows between the poles because the polar capillaries contain motor proteins that protrude from opposite ends of the problem, causing them to slip from each other,
The microtubules are like slips in the cilia and flagellum. This polar division separates the set of chromosomes in one child from another.

On a cellular basis also, the movement of chromosomes is slow. About 1 permit per minute, it takes about 10-60 . takes time

The chromosomes divide properly.

Embryos reproduce during telophase

Degeneration. chromosomes continue to shrink
until they are dispersed by the chromatin properties of the gap.

Divided during forecasting, integration and improvement of related structures. While this and many others
transformations are over, telobes – and mitosis – are over,
And the embryos of each daughter enter the second gap.
Mitosis is very precise. the result is already two nuclei.

The chromosomal make-up is similar to that of each other and that of the parent embryo, and therefore in genetic constitution. next, the two nuclei must divide into separate cells, and the cytoplasm must divide.
