Document Summary
41 synthesis : genes encoded viral by genome are unpressed replicated. Dna passes into nucleus for replication t mrna transcription by host polymerase viruses : have. 1-ve ) ss rna genome translated immediately . ss rna genome : first make after e) a y. Retroviruses have reverse transcription that synthesize dna from rna . Assembly : new nvcheocapids are constructed from coat proteins a nucleic acids viral proteins synthesised by host. In eukaryotes , nucleus occur ribosomes used to make virions in or cytoplasm . Incorporated into www. caporid not incorporated into nuclei capsid but participate in assembly. Involved in tell lysis virus release . (a) Enveloped viruses lyse host cells upon release viruses encode proteins that insert into . then nuclei capsid binds to viral proteins in. Nu4w capsid and portion of pm0 bud off host all directs: lytic cycle : phage dna synthesis of which type new phages bacterium.
