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.
