Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of ...

The origins of millions of tiny proteins in our bodies, previously assumed to be useless, have now been discovered. A study published on February 17 in the journal Molecular Cell describes how these ...

The human genome is made up of 23 pairs of chromosomes, the biological blueprints that make humans … well, human. But it turns out that some of our DNA — about 8% — are the remnants of ancient viruses ...

In an article published in the journal Nature Communications, scientists have studied a protein, called HP1, which is involved in organizing DNA. Present in both fission yeast and mammals, this ...

The genetic code acts as life’s instruction manual, telling cells how to build proteins from DNA and RNA. Though it's a marvel of molecular precision, the path it took to evolve remains unclear. Fresh ...

For decades, scientists have known that bacteria can exchange genetic material, in a process called horizontal gene transfer. This allows bacteria to rapidly evolve new traits, such as antibiotic ...

“Random DNA” is naturally active in the one-celled fungi yeast, while such DNA is turned off as its natural state in mammalian cells, despite their having a common ancestor a billion years ago and the ...

SALT LAKE CITY - Evolution is often thought of as a gradual remodeling of the genome, the genetic blueprints for building an organism. In some instances it might be more appropriate to call it an ...
