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 ...

DNA is well-known for its double helix shape. But the human genome also contains more than 50,000 unusual knot-like DNA structures called i-motifs, researchers at the Garvan Institute of Medical ...

Normally these letters combine in pairs to form the well-known double helix shape. However, some small lengths of DNA can exist as alternative shapes, which can affect how the instructions of the DNA ...

And, everyone was also taught that the double helix shape with the strands are bound by hydrogen bonds — but that might no longer be true. According to a new study published in PNAS, the key ...

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 ...

Previously known as the Double Helix Bridge ... see is that it boasts of a spiral structure which follows a helix shape over its own road. The Helix Bridge has become one of Singapore's major ...
