A Cornell-led study is challenging a decades-old explanation for how chromosomes exchange genetic material within the ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study, ...

A new analysis of ancient DNA has found that Neanderthal genomes contain 62 percent more ancestry from anatomically modern ...

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 ...

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 ...

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 ...

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 ...

Researchers are investigating the potential of CRISPR in relation to Down syndrome.
