Chromosomes: The vehicle by which hereditary information is physically transmitted from one generation to the next; in a bacterium, the chromosome consists of a single naked circle of DNA; in eukaryotes, each chromosome consists of a single linear DNA molecules and associated proteins. Read more

Prokaryotic Chromosome
 Prokaryotic Chromosome
• Found in cytoplasm.

• Circular chromosome attached to the inside of the cell membrane.

• Single chromosome plus plasmids.

• Made only of DNA.

• Copies its chromosome and divides immediately afterwards.

Eukaryotic Chromosome
Eukaryotic Chromosome
  Found in nucleus

•  Linear chromosomes

•  Many chromosomes.

•  Usually,10-50 chromosomes in somatic cells.

•  Human body cells have 46 chromosomes.

• Made of chromatin, a nucleoprotein (DNA coiled around histone proteins).

• Copies chromosomes, then the cell grows (G2 phase), then goes through mitosis to organise chromosomes in two equal groups.
