Document Summary
Reading guide for lesson 19 (pages 392, 394 396, 398 403) An infectious particle that has genes inside of a protein coat. Biologists agree they aren"t alive because they can"t carry out reproduction or metabolism outside of a host cell. In what forms may virus genomes exist? (e. g. double stranded dna) Genomes may exist in double stranded dna, single stranded dna, double stranded rna or single stranded rna. The nucleic acid that makes up its genome make it either a dna virus or a rna virus. Define the following components related to virus structure. Capsomere: the protein subunit capsids are made from. They can only replicate within a host cell. The number of host species that a virus can infect. Viruses identify a lock-and-key fit between viral surface proteins and receptor molecules of the cell. Using the text and figure 19. 4, summarize the general features of viral replicative cycles.
