A previously overlooked type of circular DNA may help explain why some children with leukaemia relapse, according to landmark research from the University of Leeds published today in Nature.

Dr. Vanessa Conn, one of the scientists on the team, said that these circular RNAs can work together and cause many changes ...

Circular single-stranded DNA viruses represent a diverse group of pathogens that possess a covalently closed, circular single-stranded DNA genome. Their small genomes belie a sophisticated ...

Swiss biochemist Friedrich Miescher was the first to identify DNA as a distinct molecule while working in Germany in 1869. But nobody knew what this molecule was until more than eight decades later.

The researchers also discovered that overactive genes within abnormal circular DNA structures in tumor cells genes drive bladder cancer resistance to therapy.
