WebAug 6, 2024 · RNA genome is an essential part of RNA viruses. In particular, non-enveloped ones convey a direct relationship between capsid proteins and RNA molecules, which was the genesis of several research routes on the assembly, disassembly and delivery functionalities of RNA inside proteinaceus capsids [1,2,3,4,5,6,7,8,9,10,11,12].RNA is a … WebThe free energy of an RNA fold is a combination of favorable base pairing and stacking interactions competing with entropic costs of forming loops. Here we show how loop entropy, surprisingly, can promote tertiary order. A general formula for the free energy of forming multibranch and other RNA loops is derived with a polymer-physics based theory. We …
