Glucose levels influence physiology and adaptation rates under replication stress, yet core adaptive mutations remain ...

Powerful new applications of what is known as next-generation sequencing are now helping with identification of degraded ...

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

Creating genomes from DNA is hugely important for managing threatened species—understanding their past and how they have ...

DNA replication is the biological process by which an exact copy of a deoxyribonucleic acid (DNA) molecule is created and it is the basis for biological inheritance. Each of the two strands of the ...

For the first time, scientists have sequenced the oldest and complete DNA set of an ancient Egyptian man, dating to when the ...

Researchers at the University of Chicago are developing a new technology that overcomes these challenges. By tagging each DNA or RNA molecule and allowing neighboring tags to interact, the technique ...

Franklin W. Stahl, an American molecular biologist whose landmark 1957-58 experiment with colleague Matthew Meselson revealed ...

A new DNA model suggests humans didn't reach Australia until 50,000 years ago, but archaeological data disagrees.

In a cell, DNA replication begins at specific locations in the genome, called "origins". Unwinding of DNA at the origin, and synthesis of new strands, forms a replication fork.

Scientists studying ancient human remains uncovered in Colombia have found that the people they were researching have no known ancestors or modern descendants.
