Q

Structure of virusis

A

Genetic material (DNA,RNA)
Membrane envelope and capsid : alayer of fatty acids coats many virusis its from host cell
Ligands : proteins that stick out of virusis surface

Q

Classifaction of virusis ( Recent )

A

Based primarily on nature of their genome and their structure
. Nucleic acid (DNA,RNA ), ((single standed, double standed, non segmented or segmented, linear or circular .))
. Virion structure (symmetry), (( icosahedlar, helical, complex)) envolped or not envolped, number or capsomers.
