Study establishes molecular forces responsible for condensation of ribonucleoprotein-RNA complexes

Researchers investigated the molecular driving forces underlying the condensation and decondensation of ribonucleoproteins using the C-Trap™. Specifically, they showed that sequence-dependent features of the RNA and ribonucleoprotein molecules partially dictate phase transitions. These findings can help scientists further understand the … Continue Reading
