Compare and contrast the chromosome structure of viruses, bacteria, and eukaryotes.
The amount of DNA per structure (virus particle, bacterium, cell) increases as one goes from viruses to eukaryotic cells.
Viral chromosomes may be composed of single strand or double strand DNA or RNA, whereas bacterial and eukaryotic DNA is double stranded.
Bacterial DNA is considered to be a covalently closed circle, the global structure of eukaryotic chromosomes are uncertain.
Some proteins are associated with viral and bacterial DNA, the regularly shaped histones of eukaryotic chromsomes are unique.
