The bacterium transferred the majority of its functional genome to your virus because it transitioned into a mitochondrion.[eighty two]
These proteins could have been transferred for the cell membrane throughout viral reproduction, enabling mobile-to-mobile fusion amongst the virus host and an uninfected cell. The theory proposes meiosis originated in the fusion among two cells infected with associated but different viruses which recognised one another as uninfected.
