Labrie, S. J. Your current browser may not support copying via this button. Proc. Because their genomes are relatively small, elucidating the genetic diversity of the phage population, deciphering their origins, and identifying the evolutionary mechanisms that shape the population would seem readily feasible. 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.
