VIRUSES: Structure and Properties Viruses consist of particles containing a nucleic acid(RNA or DNA), Which encodes all the information necessary for multiplication in the correct environment(host) The nucleic acid constitutes the viral genome and is associated with protein to form a nucleocapsid Depending on the presence or absence of lipid in the membrane, viruses are termed enveloped or nonenveloped, respectivelyVIRUSES: Structure and Properties • Viruses consist of particles containing a nucleic acid (RNA or DNA), which encodes all the information necessary for multiplication in the correct environment (host). • The nucleic acid constitutes the viral genome and is associated with protein to form a nucleocapsid. • Depending on the presence or absence of lipid in the membrane, viruses are termed enveloped or nonenveloped, respectively
