Chromosome bacteria
WebA bacteriophage, or phage for short, is a virus that infects bacteria. Like other types of viruses, bacteriophages vary a lot in their shape and genetic material. Phage genomes can consist of either DNA or RNA, and can contain as few as four genes or as many as several hundred ^ {1,2,3} 1,2,3 . WebBacterial DNA is sometimes referred to as the bacterial chromosome. Bacterial nucleoid evolutionary represents an intermediate engineering solution between the protein-free DNA packing in viruses and protein-determined packing in eukaryotes. [1]
