Describe the metaphase of Mitosis
Ans: Metaphase is the second stage of karyokinesis of mitosis. In this the karyotype of an organism is determined. In this the spindle is totally organized. Chromosomes are in highly condensed state and aligned at the equatorial region to form equatorial plate with their centromeres. The chromosomal arms are directed towards the poles. Its spindle has three types of spindle fibres formed by tubulin. They are continuous fibres extended from one pole to the other, chromosomal fibres attached to centromere of chromosomes and interzonal fibres suspended at the equatorial region (actually an artifact). The chromatids of chromosomes and the kinetochores of centromere are clearly visible.
