Question

explain briefly the stages of karyokinesis
prophase
metephase
anaphase
telophase​

Answer 1

During mitosis, when the nucleus divides, the two chromatids that make up each chromosome separate from each other and move to opposite poles of the cell. This is shown in Figure below. Mitosis actually occurs in four phases. The phases are called prophase, metaphase, anaphase and telophas

Answer 2

Karyokinesis:

division of nucleus is called karyokinesis.

It is further divided into following stages.

1.prophase

2.metaphase.

3.Anaphase.

4.Telophase.

.............

PROPHASE

=>condensatiom of cromatin material takes place.

Chromosomes become visible under light microscope.

.

METAPHASE

=>Condensed chromosomes align themselves at the equator and form and equatorial plate.

This stage is best for the study of morphology of the chromosome

.

ANAPHASE

=> the chromosome that are aligned at the equator in metaphase now gets separated due go the splitting of centromere and start moving towards the poles there centromere facing towards the poles and arms facing towards the centre

.....

TELOPHASE=>

It is the last stage of karyokinesis of Mitosis here the chromosomes have read the poles and now start losing their identity and are uncondensed again
