Genetic research does not always produce tidy answers. Sometimes it reveals traces that raise more questions than they settle ...

Researchers studied an error mechanism in DNA replication, and noticed that some errors create palindromes that can fold into hairpin structures. The complexity of ...

How much do your genes determine how long you'll live? It's a question that fascinates us, and one that's been debated for ...

In a new peer reviewed analysis, scientists quantify amino acids before and after our “last universal common ancestor.” The last universal common ancestor is the single life form that branched into ...

A duplicated gene evolved into a switch that determines sex in frogs, revealing how evolution can safely reshape critical ...

A gene that helped one species split into two species shows evidence of adapting much faster than other genes in the genome, raising questions about what is driving its rapid evolution. The paper in ...

The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers resolved outstanding questions regarding the origin of small regulatory genes, and ...
