One of the greatest challenges scientists faced while trying to develop messenger ribonucleic acid (mRNA) as a therapeutic agent was finding a way to deliver it into the body without letting it get digested.

Biochemist Dr Melissa J. Moore points out that we are actually consuming a lot of RNA whenever we eat whole protein-rich foods like meat and fish.
