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 ...
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 ...
