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

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

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 ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

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 ...

Synthetic human chromosomes may transform gene therapy by carrying large therapeutic genes without altering natural DNA. Here ...

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 ...

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 ...

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 ...
