Can Seabiscuit's DNA explain his elite racing ability?

Seabiscuit was not an impressive-looking horse. He was considered quite lazy, preferring to eat and sleep in his stall rather than exercise. He'd been written off by most of the racing industry after losing his first 17 races. ...

New species may arise from rapid mitochondrial evolution

Genetic research at Oregon State University has shed new light on how isolated populations of the same species evolve toward reproductive incompatibility and thus become separate species.

Organizing a cell's genetic material from the sidelines

A tremendous amount of genetic material must be packed into the nucleus of every cell—a tiny compartment. One of the biggest challenges in biology is to understand how certain regions of this highly packaged DNA can be ...

The cartography of the nucleus

Nestled deep in each of your cells is what seems like a magic trick: Six feet of DNA is packaged into a tiny space 50 times smaller than the width of a human hair. Like a long, thin string of genetic spaghetti, this DNA blueprint ...

Team discovers new mechanisms for DNA stability

Researchers from the University of Seville at the Andalusian Centre for Molecular Biology and Regenerative Medicine have discovered that in eukaryotic cells, the proximity of the genes to the pores in the nuclear membrane ...

Fish study shows important genome interactions in animal cells

In a new study, researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science examined how the interaction of two genomes in animal cells—the mitochondrial and nuclear genomes—interact ...
