Characteristics of Viruses

A
  • infectious, acellular pathogens
  • obligate intracellular parasites w/host a cell-type specificity
  • DNA or RNA
  • genome surrounded by protein capsid; a phospholipid membrane studded w/viral glycoproteins in some cases
  • lack genes for merry products needed for successful reproduction; requires exploitation of host-cell genomes to reproduce
