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 ...
Not all DNA is in the double helix form described in textbooks since the 1950’s. Quadruple helix DNA, also known as G-quadruplex DNA, was identified in the human genome several decades ago, and ...
Chances are you've seen an illustration of DNA's double-helix structure and even pictures of the chromosomes that make up 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 ...
The signature imagery of two DNA strands locked around each other is one that everyone has seen in school. And, everyone was also taught that the double helix shape with the strands are bound by ...

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 ...
Viewers questioned the writers over a Daily Double that was so easy, it’s in our DNA. And on a more poignant ... correctly responding “Double Helix.” The returning champ finished the round ...
