Complex RNA structures could have untapped therapeutic potential in the fight against COVID-19

To the untrained eye, the loops, kinks and folds in the single strand of RNA that makes up the coronavirus genome look like a jumble of spaghetti or tangled yarn. But to researchers like Amanda Hargrove, a chemistry professor at Duke University, the complex shapes that RNA takes on as it folds upon itself could have untapped therapeutic potential in the fight against COVID-19.
