Because each cell needs its own set of DNA, there must be two sets of DNA present in a cell before it divides into two.
The chromosomes have to split and go to opposite sides of the cell.
it divides in two parts.
The second strand of a chromosome is a copy of the genetic information for that cell. There are 2 strands so that when the cell divides, there is one copy of each chromosome for each offspring cell.
DNA replicates before a cell divides ensures that each daughter cell has a complete set of genetic material They must have an identical set of DNA.
Your DNA is copied into the new cell every time it divides
it triples in number
Before a cell can dividess, it makes a copy of its DNA (deoxyribonucleic acid).
DNA replication occurs in the nucleus of the cell - just before the cell divides.

the cell divides in two (and again and again), every 20 minuets in good conditions. The cell wont be an exact copy because before it divides it copies the DNA but sometimes it dosent match up and a the new cell will be mutated
Before a cell divides, the DNA must duplicate itself through a process called DNA replication. This process ensures that each new cell receives an identical copy of the genetic information stored in the original cell's DNA.
