Question
All chromosomes are arranged parallel to equatorial plane of cell in ______ phase of mitosis.
Advertisements
Solution
All chromosomes are arranged parallel to equatorial plane of cell in metaphase phase of mitosis.
Explanation:
During metaphase, the nuclear membrane completely disappears. Chromosomes complete condensation and become clearly visible along with sister chromatids. The chromosomes are arranged parallel to the equatorial plane of the cell. Spindle fibres are formed between the centromere of each chromosome and both centrioles.
