Cell division

Celdeling

• Each chromosome in the nucleus is copied.
• Then, two nuclei are formed.
• Next, the cell divides.
• After that, plasmagrowth occurs.

Cell division 

• During each cell division, the chromosomes are copied first.
• All the cells in your body contain the same genetic information.
