DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

The basic repeating structural (and functional) unit of chromatin is the nucleosome, which contains eight histone proteins and about 146 base pairs of DNA (Van Holde, 1988; Wolffe, 1999).

Ring-shaped extrachromosomal DNA is implicated in many cancers. Rachel Brazil talks to the scientists trying to uncover their ...

Imagine a world where we could predict the behavior of life just by analyzing a sequence of letters. This is not science ...

A DNA sequence is a specific lineup of chemical base pairs along its strand. The part of DNA that determines what protein to produce and when, is called a gene. First established in 1985 by Sir ...

based on the idea that DNA can be used as a programmable structural material for the creation of artificial, rationally designed nanostructures. The highly specific nucleotide interaction following ...

Assembling DNA nanostructures at more moderate temperatures opens up the possibility of using the structures in biomedical ...

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 ...

Every day, billions of cells in your body divide, helping to replace old and injured cells with new ones. And each time this ...
