What to know about DNA's physical properties may shape which mutations evolution preserves

Researchers from an international team, including Kaunas University of Technology, used atomistic simulations to study how the physical properties of DNA, such as shape and flexibility, influence gene expression. The study suggests that evolution tends to preserve mutations that maintain the mechanical stability of the DNA molecule.

What happened

DNA's physical properties may shape which mutations evolution preserves Sadie Harley Scientific Editor Robert Egan Senior Editor Nearly every cell in the human body contains essentially the same genetic information, yet different cells activate different…

Why it matters

For regulatory proteins to reach these genes, DNA must be accessible.

Common ground

This accessibility depends not only on the genetic code itself but also on DNA's physical properties—its shape, flexibility and ability to interact with proteins.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
