He and a colleague proved a theory advanced by the Nobel Prize winners James Watson and Francis Crick, who discovered DNA’s ...

DNA is found in nearly all living cells. However, its exact location within a cell depends on whether that cell possesses a special membrane-bound organelle called a nucleus. Organisms composed of ...

Though scientists have learned much about DNA damage and repair over the past 50 years, important outstanding questions remain. One particularly bedeviling puzzle is how a repair protein called the ...

James Watson and Francis Crick revealed the structure of DNA — the genetic instructions in all living things — 70 years ago in the journal Nature. Watson and Crick could not have succeeded ...

DNA is perhaps the most famous molecule on earth. Here we explain what it is, what it does, and how it is crucial for health.

Despite her contribution to the discovery of DNA's helical structure, Rosalind Franklin was not named a prize winner: She had died of cancer four years earlier, at the age of 37.

Explore the 5 key differences between DNA and RNA, including function, structure and location, with examples and insights from modern molecular biology.
