Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...

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, ...

An evolutionary "trap" has haunted crested and marbled newts for 25 million years: Leiden researchers have uncovered a mysterious DNA error that should not be able to arise—yet persists all the same.

Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells ...

Scientists have recently been learning more about the importance of small bits of circular genetic material known as ...
