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 make up the human genome. But where and how does the famous double helix fit into ...

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 ...

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 ...

“It’s a real paradigm shift ... The researchers watched replicating DNA from E. coli bacteria. The first step in the process always sees the double helix “unzipping” into two strands ...

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 ...
