Two Boston University doctoral students, Joshua McGee and Jack Kirsch, were creating and testing different types of RNA—strands of ribonucleic acid, built from chains of chemical compounds called nucleotides that help carry out genetic instructions in cells. They were determined to see whether RNA sequences crafted with small changes to their nucleotides can still work.
