The Science of Subtlety

Weak interactions between biomolecules hold tantalizing mysteries

IBRAHIM CISSÉ, MIT ASSISTANT PROFESSOR of physics, is devising new ways to look inside a living cell to see how DNA is read and written out as messenger RNA, the instructions used by the cell to make the molecular machines that do the cell’s work. An understanding of how cells perform this essential task of transcribing DNA has obvious practical implications. Many pharmaceuticals aim to control gene expression, and finding new ways to regulate genes is a priority for drug developers and bioengineers.
