Scientists have created an entirely new kind of DNA with eight chemical letters instead of four — and it still forms a double ...

DNA stands for Deoxyribonucleic Acid, the molecule that carries the genetic code of all living things. It’s found in every cell and determines everything from your looks to your body functions. In ...

While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that ...

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 ...

Cockayne syndrome (CS) is a rare disease that causes short stature, premature aging (progeria), severe photosensitivity, and moderate to severe learning delay. A new study by researchers from the ...

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

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 DNA inside our cells is constantly being damaged, and one of the worst kinds of damage is a double-strand break—when both ...
