Bacteriophages genomes arguably also harbor the greatest genetic novelty in the biological world, in that most of their encoded genes (perhaps as much as 80%) are unrelated to known proteins, and are of unknown function. Although most known phages harbour genomes that are shorter than 200 kb packaged into capsids with a diameter under 100 , more and more extremely large phages are being discovered. 79, 1496714970 (2005).

Their average size is substantially less than that of core genes, often by nearly a factor of two, and it has been suggested that they may correspond to individual functional protein domains [35,36].

T2 phage had very high genomic sequence similarity to SV76 (99.99% identity), so we performed host range analysis of T2 with the same bacteria strains to see whether the genomic similarity translated to host range phenotypic similarity.
