Episode notes
Mimivirus' Genes
- The giant virus, named Mimivirus, had over 1,000 genes, unlike typical viruses with around 10.
- Its DNA resembled viral DNA, not bacterial DNA.
Virus Factory
- Mimivirus builds a 'virus factory' inside its amoeba host instead of dispersing its contents.
- This factory takes in components and releases new Mimivirus particles.
Mamavirus
- Scientists found another, even bigger giant virus, Mamavirus, also in a cooling tower.
- Mamavirus had similar behavior but even more unique genes.
