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 ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

As the cell proceeds through the stages of cell division (from left to right: interphase, prometaphase, metaphase, and anaphase), chromosomes become progressively more compact through a combination of ...

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 ...

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 team of researchers have generated the first complete chromosome sequences from non-human primates. Published in Nature, these sequences uncover remarkable variation between the Y chromosomes of ...

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 ...

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

If you are anything like us, whenever you plan a journey, you spend a remarkable amount of time thinking about the start and ...

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

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