Pandoravirus, bigger and unlike anything seen before
The discovery of the giant Mimivirus and Megavirus amazed virologists (and also many others). Their virions (750 nanometers) and DNA genomes (1,259,000 base pairs) were the biggest ever discovered, shattering the notions that viruses could not be seen with a light microscope, and that viral genomes were smaller bacterial genomes. Now two even bigger viruses have been discovered, which are physically and genetically unlike any previously known viruses. They have been called Pandoraviruses.
