Question

What happens when the cell copies its chromosomes

Answer 1

friend we studied in cell cycle that it completes in two steps.

1) Inter phase ( G1, Gs, G2 phases)

2) division phase ( Mitiosis and meosis)

* G s phase;

during G s phase cell continous start increasing in size also in this phase cell replicates it's chromosomes. and the centrosomes are divided into centrioles for spindling.

Answer 2

During mitosis, the chromosome copies separate the nucleus divides and the cell divides. This produces identical two cells called daughter cells. The main purpose of mitosis is for growth and to replace worn out cells.
