Viruses...linear or circular?

All DNA viruses have linear DNA except:
  1. the 2 "-oma" viruses: papillomavirus and polyomavirus (circular) [oma reminds you of tumors, which are generally round]
  2. hePAdna virus (PArtially circular).
 All RNA viruses have linear RNA except for the following circular viruses:
  1. Arenaviruses: an "arena" is round
  2. Bunyavirus: "bunions" are round
  3. Deltavirus: the greek letter delta "δ" is round
