Internationally renowned microbiologist, Peter Palese, PhD, pioneered the field of reverse genetics for negative - strand RNA viruses, which allows the introduction of site - specific mutations into the genomes of these viruses.

Unlike DNA viruses, which contain two copies of their genetic information, RNA viruses are single - stranded.

As a result, copying is sloppy, and so each new generation of RNA viruses tends to have lots of errors.

This viral genetic jumble has given Marco Vignuzzi, a virologist at the Pasteur Institute in Paris, a way to predict the future evolution of RNA viruses like chik.

Filoviruses are RNA viruses that don't carry the gene for reverse transcriptase, yet that hasn't stopped them from somehow leaving their mark.

Researchers long have believed that to accomplish this feat, RNA viruses had to carry the gene for an enzyme, reverse transcriptase, to convert their RNA into DNA.
