The bacterial chromosome is a double-stranded, circular DNA molecule associated with a small amount of protein. Eukaryotic chromosomes have linear DNA molecules associated with a large amount of protein. The formation of a highly organized DNA-protein complex, termed as chromatin, which is a nucleoprotein complex completes the packing..
