When molecular biologist Francis Crick tripped on the psychedelic drug LSD in 1953, his mind famously pulled together all of his previous research on human DNA to conceive of the image of a double ...

Scientists have a new theory about the structure of DNA. Two strands of alternating sugar (deoxyribose) and phosphate groups make up the DNA double helix, and the strands were thought to be linked by ...

A study of octopus DNA may have solved an enduring mystery about when the rapidly melting West Antarctic ice sheet last collapsed, unlocking valuable information about how much future sea levels may ...

A Wellington School student's success in unraveling a DNA knot-theory problem earned her a spot as one of 40 high school students nationwide -- and the only one from Ohio -- named finalists in the ...

R-loops are structures that form when a strand of RNA (red) forms a stable structure with double-stranded DNA, causing one strand of the DNA to form a loop. R-loops are associated with gene ...

DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. The authors have found a flaw in the most common model for DNA elasticity, a discovery ...

A simple roadside weed may hold the key to understanding and predicting DNA mutation, according to new research from University of California, Davis, and the Max Planck Institute for Developmental ...

DNA usually likes to follow rules. Strands of DNA are copied somewhat faithfully, and the copies are passed from parents to offspring, thus driving evolution as we know it. But, according to new ...

The leading explanation for how life started on Earth is the RNA world hypothesis. The theory posits that life later evolved to use DNA because of the relative instability and poor catalytic ...

In 2010, small cores of permafrost sediments were collected by a team at the University of Alberta from gold mines in the Klondike region of central Yukon. They had remained in cold storage until ...

DNA coding theory bridges the disciplines of mathematics, computer science and molecular biology by applying advanced algebraic and combinatorial techniques to the design of nucleotide sequences. This ...
