That would be an interesting read, the reason that I do not like the word insertions with people that know nothing to little about the actual science, is because the virus has actually removed genetic material, and substituted it's own, the amount of genetic material has not changed. So editing, is the word that I think should be used with scientific illiterate types.
In other words, the DNA is still the same length, but it has been edited, or changed by the virus. The virus has removed genetic material for it's own use, and inserted, an edited version of it's own in it's place.
At least that is the way that I visualize it.
I'd suspect we will eventually find all sorts of "insertions" that involve total replacement, to rewriting, to "editing", both random and directed.
