Chunks of flipped DNA appear to accelerate evolution in fish. This discovery could reshape our understanding of how ...

Cod used to be giants. With their impressive size—over a meter in length and weighing up to 40 kilograms—and abundance, they, ...

Decades of overfishing have altered the genetic makeup of Baltic cod, shrinking their size and threatening their recovery.

In the house finch, this new approach revealed a DNA inversion that has existed for millions of years—and that may have ...

The difference is called a genetic inversion, a long piece of DNA that has been clipped out of a chromosome at both ends and then reinserted essentially upside down.

“With an inversion, big chunks — in this case, 30 million DNA bases — of the chromosome get flipped backwards,” he says. And this inversion in T. knulli, the team determined, is ancient. “We think it ...

The condensation of stiff, highly charged DNA molecules into compact structures by condensing agents ranging from multivalent ions1 to small cationic proteins2,3 is of major biological and ...
