What causes cell multiplication?
How chemicals affect the genetic make-up of cells: mutagenesis

This process is specific to all cells in the body, with the exception of sex cells.

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...
