During cell multiplication, each cell (mother cell) divides into two daughter cells with identical genetic material (diploid cells).
The process of mitosis is divided into four phases:
the nucleus dissolves and the DNA is distributed in the cytoplasm (prophase);
chromosomes are replicated and reunited at the center of the cell on a bundle of microtubules attached to two centrosomes (metaphase);
each group of...
