Document Summary
Viruses: viruses are very unique, only thing that have genomic information: rna, phage. Has to get through the bacterial cell wall. Has apparatus to attach and punch hole to infect: plant viruses tend to not have an envelope. Infect cells depending on insects and agricultural: vary in terms of size and morphology, central dogma has exceptions i. ii. Technology advances, get more information: process of science, structure, nonenveloped virus. Nucleic acid and protein: phage e, envelopes or coats. In bacteria the outermost structure is the cell wall that has to be gotten through: many viruses are bound by an outer, flexible, membranous layer called envelope. Symmetry is not determined by presence or absence of an envelope. Icosahedral capsids: regular polyhedron with 20 triangles, viral envelopes and enzymes, why is it so hard to treat viruses i. ii. Viruses do not have mitochondria: use the host cell for power, viruses use up host"s atp.
