Some of us don't know, so the extra detail is appreciated :)
Interesting re: the thiophosphate group. It sounds like it just floods your body with some mRNAs complementary to the viral mRNA that blocks it from getting turned into proteins by your cells' ribosomes?
Yes, pretty much; almost like NOPing out code in binary patches. However double check about the thiophosphates. I might be wrong. It is either Morpholinos are blockers and thios are promoting destruction of the mRNA or the opposite.
