Researchers explore a basic building block used in the fabrication of many DNA nanoforms. Known as a Holliday junction, this nexus of two segments of double stranded DNA has been used to form ...

Inside every human cell, six feet of DNA folds into a nucleus that is only a few micrometers wide, yet still manages to ...

DNA is the genetic material used by every living organism. But, in a few edge cases, the four bases of DNA—adenine, thymidine, cytosine, and guanine—undergo chemical modifications. And in viruses, ...

For sheer versatility, there’s no molecule quite like DNA. The iconic double-helix carries the genetic blueprint for living forms ranging from single-celled organisms to human beings. Recently, ...

The technique, known as DNA origami, promises to bring futuristic microelectronics and biomedical innovations to market. Hao Yan, a researcher at Arizona State University’s Biodesign Institute, has ...

The world’s most famous molecule – the DNA double helix – sometimes doubles up again. Researchers have now found this quadruple-stranded form in healthy human cells for the first time. Four-stranded ...
