Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...

How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help ...

A base editor rewrote a single DNA letter while editing human embryos, and every chromosome held even as mosaicism keeps a ...

Chromosome fusion represents a major form of karyotype evolution. However, it remains unclear how cells adapt to drastic changes in chromosomal organisation and overcome the topological challenges ...

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells by co-opting a process used to maintain cellular identity through ...

A new study conducted on roundworms finds that a common plastic ingredient causes breaks in DNA strands, resulting in egg cells with the wrong number of chromosomes. Monica Colaiácovo of Harvard ...

Neanderthals, the closest cousins of modern humans, lived in parts of Europe and Asia until their extinction some 30,000 years ago. Genetic studies are revealing ever more about the links between ...

Findings published in the journal Nature show that 'SIRT7', a protein involved in how cells respond to stress and ageing, ...

(Cavan Images/Getty Images) The human Y chromosome is shrinking. In the next 5 million years or so, some geneticists think ...

The 2010 discovery that early humans and Neanderthals once encountered one another and had babies was a scientific bombshell that electrified the field of human origins. Now, geneticists at the ...
