The incredible ways of DNA replication

For over 30 years, Professor Michael O’Donnell, based at the Rockefeller University in New York, has focused on the mechanisms involved in the duplication of genetic material in cells, a process known as DNA replication. Professor O’Donnell’s work spans from the early 1990s, when his team was the first to discover a ring-shaped protein that encircles DNA and clamps the replication machine to DNA. Most recently, the team has been studying the proteins involved in mammalian DNA replication.
