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 ...
Pancreatic cancer is one of the deadliest cancers worldwide, with a five-year survival rate of 13%. This poor prognosis stems ...
Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the effects aren't just skin deep. Inside the body, DNA is literally being torn ...
Pancreatic cancer’s deadly resilience may be tied to extrachromosomal DNA, which allows tumor cells to rapidly adapt to ...
Pancreatic cancer is one of the deadliest cancers worldwide, with a five-year survival rate of 13%. This poor prognosis stems from both late detection ...
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 ...
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 ...
With the C-Trap, he could see individual molecules of HELQ travelling along single DNA strands, unwinding them from their usual helix shape. Surprisingly, HELQ travels much faster along the DNA ...
Scientists found that fast-evolving DNA shaped human brain development but might also increase risks for mental disorders.
In an article published in Molecular Cell, scientists have discovered how the three-dimensional organization of DNA in our cells influences genes across multiple generations. By manipulating the ...
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 ...
“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, ...
