The Mimi virus is of particular interest because of it’s incredible size(for a virus).
With a genome twice as large as the next-largest virus and a capsid of diameter 400
nanometers, the Mimi virus might hold an important clue for biologists. What is the
significance of the virus?
It is large enough that scientists can observe viral reproduction and learn how
other pathogens, like HIV, spread.
It is a bacteriophage that attacks every bacterial cell due to a large variety of extracellular markers.
The virus' rapid evolution makes it an easy test subject for many biological
experiments.
It represents a "missing link" in the evolution of bacteria from less
complicated organisms.
