viral replication is nuclear. entry into the host cell is achieved by attachment of the viral fibers to the host car adhesion receptor. subsequent binding of the penton protein to host integrin entry receptors mediates internalization into the host cell by clathrin-mediated endocytosis of the virus and fiber shedding. some serotypes also seem to use macropinocytosis. disruption of host endosomal membrane by lytic protein vi releases the viral capsid in the cytosol. microtubular transport toward nucleus of the viral genome still protected by the core protein vii and a partial capsid mainly composed of hexons and protein ix. docking at the npc and capsid disruption. import of the viral genome into host nucleus mediated by core protein vii. transcription of early genes (e genes) by host rna pol ii: these proteins optimize the cellular milieu for viral replication, and counteract a variety of antiviral defenses. intermediate genes activate replication of the dna genome by dna strand displacement in the nucleus. expression of l4-22k and l4-33k causes early to late switch. transcription of late genes (l genes) by host rna pol ii, mostly encoding structural proteins. host translation shutoff performed by the viral 100k protein. assembly of new virions in the nucleus. virions are released by lysis of the cell. virion maturation by the viral proteasehost receptors, which mediates clathrin-mediated endocytosis. replication follows the dna strand displacement model. dna templated transcription, with some alternative splicing mechanism is the method of transcription. translation takes place by ribosomal shunting. the virus exits the host cell by nuclear envelope breakdown, viroporins, and lysis.

rbdv is non-enveloped with an isometric protein coat about 33 nanometres in diameter. inside the protein coat is the viral genome, which is bipartite, with the rna strands referred to as rna-1 and rna-2. rna-1 is 5,449 nucleotides in length and contains one open reading frame (orf) that encodes for a combined protein that has methyltransferase, helicase, and an rna-dependent rna polymerase domains. rna-2 is 2,231 nucleotides in length and contains two orfs, one at the 5' end and the other at the 3' end. the first orf encodes for a cell-to-cell movement protein, while the second orf is expressed as a subgenomic rna strand. this strand, rna-3, is 946 nucleotides in length and encodes for the coat protein. infection has been shown to not occur if rna-3 is either not present or is sufficiently damaged.
