Explain the third stage of mitosis-anaphase with diagram
Answers
↪ ANAPHASE:-
The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibres. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

Answer:
Explanation:
Anaphase represents the segregation of duplicated chromosome.This segregation occurs becoz of retraction of spindle fibers.These chromatids after segregation reach opp. poles of the cell. When they reach opp. poles of the cell they are reffered as Chromosomes. Now, the opp. poles of a cell recieve 46 chromosomes.
