As noncellular, submicroscopic agents that do not possess organelles for independent living and have to rely on cellular machinery of another organism for replication and maintenance, viruses are notably small. In fact, with a dimension of 20-400 nm (or 10"8-10"6 mm), viruses are 10-100 times smaller than prokaryotes (10-7-10-4 mm) and 1000 times smaller than eukaryotes (10-5-10-3 mm). Being able to pass through conventional sterilizing filters (0.2 μm), viruses were initially referred to as filterable agents.
