Usually infectious, but can also be not infectious (not infectious one called defective; d. i. ) Either rna or dna depends upon the virus. Protein shell that surrounds the genome in the core. Give specificity of infection in the context of the ii. Give specificity of infection in the context of the receptor. Tropism the growth/ turning of all or part of an organism in a particular direction in response to an external stimulus. iii. When virus replicate in the cell, only the genome info in the capsid got copied iv. As they replicate, some part of virus needs release. Envelope a. b. c. d. lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells the virus envelope is derived from the host cell membranes.
