The double helix is a description of the molecular shape of a double-stranded DNA molecule. In 1953, Francis Crick and James Watson first described the molecular structure of DNA, which they ...

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 ...

Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that comprise the human genome. But where and how does the famous double helix fit into ...

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 ...

One film that successfully depicts the competitive nature of scientific research and the sacrifices that scientists make for their careers is Life Story: The Race for the Double Helix, a 1987 made-for ...

Feedback, a Lego fan, delves into a new science-related set, and learns that the model of a DNA double helix is the wrong way around. Time for some jokes about mirror organisms... Feedback may be ...
