Key findings highlight the role of horizontal gene transfer, the incorporation of foreign bacterial genetic material into the beetle genome, which is thought to be the result of earlier symbioses.

Each gene tells a cell to make a specific molecule, but this isn't performed by the DNA itself. Instead, the information is relayed to cellular machinery by a molecule called messenger RNA.

If you'd like to learn more about your health, heritage and family history, an at-home DNA test can help you do just that. Justin Jaffe is the Managing Editor for CNET Money. He has more than 20 ...

Yet humans share upwards of 95% of our genome with chimpanzees, our closest living relatives. Each gene tells a cell to make a specific molecule, but this isn’t performed by the DNA itself. Instead, ...

"This is suggesting that there is more plasticity in our DNA than we thought before," says study leader Dusan Bogunovic, professor of pediatric immunology at Columbia University Vagelos College of ...

The host has to accommodate a suppressed immune system and potentially more viral genome invasions," said Ruiqi Li. The study also discovered that giant clams have fewer genes related to body ...

A piece of genetic code from another chromosome, or even from a virus, can embed itself into the DNA chain, changing how it—and we—function. In 2024, however, Weichen (Arthur) Zhou and Ryan ...

Before we understood that DNA was the genetic code, scientists knew that bacteria transferred it between cells. In 1928, 25 years before the structure of DNA was solved, British bacteriologist ...

They’ll check the fetus for mutations in the NOD2 gene. Finding a mutation in the gene doesn’t mean a diagnosis of Crohn’s disease. It only indicates an increased risk for developing the ...
