Cells can make exact copies of themselves.
Prokaryotes have a single, simple circular double helical DNA molecule to store genetic information.
The cell cycle is the complete process of replicating the DNA, coiling it up tightly, adding new proteins to make a duplicate chromosome. The process of duplicating the chromosomes is called mitosis . Mitosis, followed by sucessful cell division produces two identical cells. In reality, eukaryotic organisms have more than one chromosome, We have 23 different types of chromosomes. Each of these 23 chromosomes is slightly different in appearance.
