I started life as a chemistry student but realized that the chemistry of life was more of interest. Viruses straddle the line between a living and non-living life cycle and so are fascinating objects, especially in their ability to encode the repeated building of the non-living protective “lifeboat” we call a virus.

The virion is the “lifeboat” protecting the viral nucleic acid through escape from one cell and invasion of the next…
