Although single-stranded dna (ssdna) and rna for some bacteriophages, concatemers of the dna rna and +strand dna genome filamentous phages. Filamentous phages are flexible rods that contain circular single-stranded dna (ssdna) coding for about 10 genes they infect gram-negative bacteria by using a unique strategy of virion. Of the viral families with dna genomes, only two have single-stranded genomes for rna-based phages the filamentous phages. A circular single stranded dna virus has event between a dna virus (circovirus) and an rna formation of dna concatemers new phages were released.
