Penn study identifies molecular guardian of cell’s RNA

PHILADELPHIA – When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins – they have to be processed first. One of those processes is called splicing, a mechanism by which non-coding gene…

Would a molecular horse trot, pace or glide across a surface?

RIVERSIDE, Calif. — Molecular machines can be found everywhere in nature, for example, transporting proteins through cells and aiding metabolism. To develop artificial molecular machines, scientists need to understand the rules that govern mecha…
