Beyond the ladder-like structure described above, another key characteristic of double-stranded DNA is its unique three-dimensional shape. The first photographic evidence of this shape was ...
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 ...

Interesting Engineering on MSNUS supercomputer with 200,000 trillion moves per second shows how DNA repairs itselfScientists have tapped into the Summit supercomputer to study an elaborate molecular pathway called nucleotide excision ...
Linus Pauling discovered that many proteins take the shape of an alpha helix, spiraled like a spring coil. In 1950, biochemist Erwin Chargaff found that the arrangement of nitrogen bases in DNA ...
But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...
This showed that DNA had a helix shape. Without her knowledge, one of her colleagues showed the picture to James Watson. When he saw it, he knew that his and Francis Crick’s theory about the ...
Scientists found that fast-evolving DNA shaped human brain development but might also increase risks for mental disorders.
“I’m going to have a heart-attack!!” he wrote in an email to his advisors in March 2012. In the end, he concluded that roughly 178 million years ago, some fern took in a bit of hornwort DNA and boom, ...
Researchers at Georgia State University used the Summit supercomputer to study an elaborate molecular pathway called ...
