Unusual DNA folding increases the rates of mutations Date: February 9, 2021 Source: Penn State Summary: DNA sequences that can fold into shapes other than the classic double helix tend to have ...

DNA sequences that can fold into shapes other than the classic double helix tend to have higher mutation rates than other regions in the human genome. New research shows that the elevated mutation ...

The DNA in our cells spends most of its time in the familiar double helix structure. ... To be clear, not just any piece of DNA can fold itself into the i-motif shape.

Dec. 9, 2024 — Helical structures are ubiquitous across biology, from the double-stranded helix of DNA to how heart muscle cells spiral in a band. Inspired by this twisty ladder, researchers ...

A DNA double helix is made of two strands running in opposite directions. ... and speeds can vary by about ten-fold. Kowalczykowski compared DNA replication to driving on a congested California ...

Since the discovery of the double helix structure of DNA nearly 70 years ago, scientists have worked to understand how the two strands of DNA are opened to access the genetic information they ...

When most of us think of DNA, we think of that iconic double helix shape. But when you zoom out, DNA gets a lot more complicated. "When Watson and Crick described the DNA double helix, they were ...

DNA doesn't just coil in the iconic double helix immortalized in every high school biology textbook. It also loops into a menagerie of fantastical shapes, new research finds.

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred to as non-B DNA—have been implicated as regulators of cellular ...

New York — The discovery of DNA's double helix structure 70 years ago opened up a world of new science — and also sparked disputes over who contributed what and who deserves credit.

The book is "The Secret of Life: Rosalind Franklin, James Watson, Francis Crick, and the Discovery of DNA's Double Helix." Howard Markel, always great to see you. Dr. Howard Markel: ...

The double helix shape is commonly seen inside living organisms, but this is the first time it has been observed in the cosmos. "Nobody has ever seen anything like that before in the cosmic realm ...
