Comments P.26 2nd paragraph: "Following successful adsorption, the virus genetic material, either DNA or RNA, enters the host. For phage, the genetic material is injected as a result of biophysical and biochemical processes. Viral heads are pressurized for example, the internal pressure exerted by the phage λ genome on its capsid is estimated to vary between 20 and 60 atm (BNID 113061). Internal pressures inside capsids are higher than that of the bacterial cytoplasm, estimated to vary from a few atmospheres to approximately 10 atm (primary source). The pressure in a virus head represents the end results of packaging, with the aid of a “packaging force” (Inamdar et al. 2006)."
