Researchers studied an error mechanism in DNA replication, and noticed that some errors create palindromes that can fold into hairpin structures. The complexity of ...
Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...

Ghost lineages: The ancient DNA hiding in our genes today?
Fragments of DNA from long-extinct human relatives still circulate in modern genomes, and in some cases they do more than ...

Scientists discovered a ‘ghost’ genetic signal in humans with no known fossil origin
Genetic research does not always produce tidy answers. Sometimes it reveals traces that raise more questions than they settle ...
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 genome-wide analysis has identified genetic variants that have different effects on human growth and metabolic traits depending on their parental origin. Often, the same variant will push traits 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 ...
