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 ...

Fluorogenic DNA aptamers produce light only in the correct structural state, enabling programmable molecular logic, ...

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 ...

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, ...

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 ...

The fundamental organization of the DNA in active and inactive compartments arises immediately after fertilization of the oocyte, even before genes are activated. The discovery will lead to a better ...

DNA molecules extracted from fish sperm is being used to develop new types of flame retardant materials. Scientists recently discovered that DNA is highly resistant to fire. And in a series of ...
