Question

explain the anaphase1 with labelled digram​

Answer 1

Answer:

In anaphase, cohesin proteins binding the sister chromatids together break down. sister chromatids (now called chromosomes) are pulled toward opposite poles.

...

In prophase,

chromosomes condense and become visible.

spindle fibers emerge from the centrosomes.

nuclear envelope breaks down.

nucleolus disappears

Answer 2

Answer:-

Anaphase 1:

$\longmapsto$ The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes.

$\longmapsto$ The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibres.

$\longmapsto$ During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance.

$\longmapsto$ At the end of anaphase, each pole will get one set of daughter chromosomes.

$\longmapsto$ It is the shortest phase and is also known as a migratory phase.
