DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

Although DNA is often found as a single-stranded polynucleotide, it assumes its most stable form when double stranded ... phosphate chain runs in the 5' to 3' direction, whereas the other's ...

For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

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 ...

that the DNA molecule exists in the form of a three-dimensional double helix. More than 50 years passed before the significance of Miescher's discovery of nucleic acids was widely appreciated by ...

Scientists have provided the most detailed account yet of the earliest stages of DNA replication, an essential process 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 ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

Scientists at the University of Leicester have captured the first detailed “molecular movie” showing DNA being unzipped at ...

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 ...

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.
