This Concept Map, created with IHMC CmapTools, has information related to: Viral Structure cmap Grad Med Micro_2016 presentation, may have an envelope lacks an envelope naked virus, protein subunits called protomers that assemble into capsomeres symmetry helical, an intact infectious viral particle consists of may have an envelope, genome can be single molecule or multiple molecules (segmented), Viral Structure Virion an intact infectious viral particle, lipid bilayer surrounds nucleocapsid (icosahedral, helical or complex) attachment proteins peplomers (glycoproteins) encoded by viral genome and embedded envelope bind the virus to receptors on susceptible host cells, an intact infectious viral particle consists of genome, enveloped virus composition lipid bilayer surrounds nucleocapsid (icosahedral, helical or complex), protein subunits called protomers that assemble into capsomeres symmetry icosahedral, naked virus composition a genome surrounded by protein (capsid), genome function codes for: synthesis of viral components; viral enzymes for replication and host immune evasion, capsid description a protein shell surrounding the genome, a protein shell surrounding the genome compostion protein subunits called protomers that assemble into capsomeres, may have an envelope origin derived from host cell membranes by a process called budding, capsid function deliver genome into the cell, may have an envelope has an envelope enveloped virus, genome can be linear or circular molecule, genome can be single-stranded or double-stranded DNA or RNA, an intact infectious viral particle consists of capsid, capsid function protects viral genome
