Chances are you've seen an illustration of DNA's double-helix structure and even pictures ... is a special kind of DNA known as Z-DNA. The DNA molecule is made up of four bases -- adenine (A ...

In 1953, Francis Crick and James Watson described the molecular shape of DNA as a "double helix." Double-stranded DNA is composed of two linear strands that run opposite to each other, known as ...

In 1970, biochemist Robert Wells of the University of Alabama at Birmingham saw something strange in his X-ray images of a new synthetic DNA polymer. The DNA molecule was composed of the traditional ...

The results presented here will allow better assessment of triple helix-forming propensities of DNA repeat sequences. They are also of value for the design of clamp-type TFOs 6,8 with increased ...
