Draw labelled diagrams and write explanation Draw the diagram of metaphase.

Answer»

Metaphase: 

a. Chromosomes are completely condensed and appear short. 

b. Centromere and sister chromatids become very prominent. 

c. All the chromosomes are arranged at equatorial plane of cell. This is called metaphase plate. 

d. Mitotic spindle is fully formed in this phase. 

e. Centromere of each chromosome divides horizontally into two, each being associated with a chromatid. 

[Note: The centromeres divide at the beginning of anaphase so that the two chromatids of each chromosome become separated from each other.
