Richard J. Roberts (British molecular biologist)

Major discovery

In the late 1970s Roberts discovered that, contrary to earlier expectations, many genes in eukaryotes are interrupted by noncoding segments called introns. He showed that precursor messenger RNA is processed by removing these introns and joining the remaining pieces (exons) in a process called RNA splicing. That finding, for which he shared the 1993 Nobel Prize in Physiology or Medicine with Phillip Sharp, revealed that a single stretch of DNA can give rise to different mRNA products through alternative splicing and thus expand protein diversity.

Career and affiliations

Roberts has held positions in major research centres and academic institutions. His appointments have included work at Harvard University, laboratory research at Cold Spring Harbor Laboratory, and roles connected to biotechnology firms such as New England Biolabs. Over decades he combined basic research with involvement in applied molecular techniques and reagents used across genetics laboratories.

Impact and importance

The recognition that genes may be split into coding and noncoding parts reshaped genetics, genomics and biomedical research. Understanding introns and splicing is central to interpreting gene expression, diagnosing inherited disorders, and developing therapies that target RNA processing. Roberts' work is taught as a core concept in molecular biology courses and underpins much of modern genomics.

Distinctions and public roles

• Recipient of the Nobel Prize for physiology or medicine (1993) shared with Phillip Sharp.
• Fellow of scientific societies and widely cited researcher in molecular genetics; recognized by peers for the discovery of introns and splicing.
• Associated professionally with institutions including Harvard University, Cold Spring Harbor and companies such as New England Biolabs.

Roberts' contribution remains a cornerstone of how scientists understand gene structure and regulation.
