The possibility that some of these small genes provide no selective benefit to the phage that carries them cannot be ruled out, but their generally orderly arrangement on the genome, with good translation start sequences argues against their being disorganized junk DNA. Bacteriophages offer a special perspective on the diversity, origins, and evolution of viruses, not only in their tremendous abundance there are more than 1031 phage particles in the biosphere but in their distant origins, likely more than three billion years ago [1,2]. and transmitted securely.

As with the head genes discussed above, this more extensive case of genetic linkage can be understood in terms of the interactions of the encoded proteins: T4s DNA replication proteins form a complex, the nucleotide metabolism genes probably form a complex that feeds precursors into the DNA replication machine.

Newly acquired DNA thus provides a reservoir of genetic information for potential future use, rather than being selected for immediate utility. 37, 632639 (2019). 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. Casjens S. Prophages and bacterial genomics: what have we learned so far? An intriguing possibility, whether they are providing a selective benefit or not, is that these genes could serve as a gene nursery, where novel genetic functions could be built by recombination and mutation among genetic sequences that have no essential role in phage survival.
