Question

In which stage of cell division, division of matrix of chromosome occurs?

• A. Late prophase
• B. Early metaphase
• C. Late metaphase
• D. Anaphase

Answer 1

Answer: (C)

Late metaphase

During late metaphase, a chromosome consists of two chromatids joined together by the centromere, and get arranged at the equatorial plate. The spindle fibres contract, separating each chromosome into its two chromatids, or "single" chromosomes. One of each pair of chromatids goes to each of the two new cells that form. So, if the cell had four double chromosomes before metaphase, the new cells will each have four single chromosomes. The number of chromosomes remains unchanged, the double chromosomes have simply become single chromosomes.

So, the correct answer is option C.
