 Replication follows the DNA strand displacement model, and DNA-templated transcription is the method of transcription.The virus exits the host cell by lysis via lytic phospholipids, with passive diffusion being the mechanism behind transmission routes.In three dimensional recreations of PBCV-1 ("Paramecium bursaria chlorella virus"), a prototype of chlorovirus, it is seen that the spike first contacts the host’s cell wall and is aided by fibres in order to secure the virus to the host.
