Watson and Crick ultimately used Franklin's images, along with their own evidence for the double-stranded nature of DNA, to argue that DNA actually takes the form of a double helix, a ladder-like ...

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 ...

his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double helix. More than seven decades later, mathematician Robert Monjo believes he has ...

DNA is a complex molecule that consists of two strands coiled around each other to form a double helix structure. Comparison of a single-stranded RNA and a double-stranded DNA with their corresponding ...

A DNA double helix is made of two strands running in opposite directions. Each strand is made of four bases -- A, T, C, and G -- that pair up in specific ways to form rungs along the strands.

MSK researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a ...

The King's team took an experimental approach, looking particularly at x-ray diffraction images of DNA. In 1951 ... interlocked in the middle of the double helix to keep the distance between ...

The backbone of the DNA double helix consists of alternating phosphate and deoxyribose sugar molecules. Interlinking bases hold the two sides together. As A is complementary to T and C is ...

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 ...
