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 replication ...

To our immune system, a potentially lifesaving gene therapy can look a lot like a dangerous infection. That's because most genetic medicine uses viruses or double-stranded DNA to deliver genetic ...

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...

A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA - loops of DNA found outside of regular chromosomes - are twice as ...

In September 1970, Janet Mertz joined the biochemistry department at Stanford University. She was one of only six new graduate students in the department and the first female one admitted in nine ...

The authors used a combination of super-resolution imaging techniques and liquid pressure flow to fine-tune the stretch ratio of a DNA molecule, improving the lateral resolution of side-by-side ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs ...
