AB  - The  classification  of  viruses  is  based  on  chemical  and  morphologic  criteria.  The  two  major  components  of  the  virus  used  in  classification  are  (1)  the  nucleic  acid  (its  molecular  weight  and  structure)  and  (2)  the  capsid  (its  size  and  symmetry  and  whether  it  is  enveloped).  A  classification  scheme  based  on  these  factors  is  presented  in  Tables  31–1  and  31–2  for  DNA  and  RNA  viruses,  respectively.  This  scheme  was  simplified  from  the  complete  classification  to  emphasize  organisms  of  medical  importance.  Only  the  virus  families  are  listed;  subfamilies  are  described  in  the  chapter  on  the  specific  virus.  Figures  31–1  and  31–2  show  a  classification  outline  for  DNA  viruses  and  RNA  viruses,  respectively,  based  on  the  type  of  genome,  the  nature  of  the  nucleocapsid,  and  whether  an  envelope  is  present.
