DNA is a double helix.”This is a fact so famous that it now appears in middle and high school textbooks. However, when you learn the details of how this shape was discovered, you realize it is not a ...
The researchers also found that DNA molecules do not all pair with the same strength. Some DNA sequences form much stronger ...
Bacteria have transformed some viruses — now called gene-transfer agents — into a means of exchanging genetic material among ...

Life uses four DNA letters, but scientists made an eight-letter system work
Every known organism writes genetic information with four DNA letters, but laboratory chemistry is not limited to that ...
Every person alive carries between 0.5% and 1% of their genome from a hominin that has no name, no fossils, and no sequenced ...
A new study finds that when p53, one of the most important cancer-protecting genes, stops working, cells produce too much RNA ...
Did DNA and life itself really arise spontaneously in puddles or undersea vents 3.8 billion years ago, or is this a sign that ...
"The real 'aha' moment came from biochemical experiments and the cryo-EM structure. Hiroshi Nishimasu and his team could actually see the DNA product sitting in the enzyme, and the structure put these ...
A newly mapped step in DNA replication suggests that strand separation begins at a precise junction between two helicase rings. Credit: Shutterstock Researchers mapped where DNA first opens and how a ...
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...
A bowhead whale calf born the year Thomas Jefferson took office could, in principle, still be alive today, drifting under the Arctic ice with a harpoon point from the 1840s lodged in its blubber. The ...
