The genetic diversity of the largetooth sawfish (Pristis pristis), a critically endangered ray, has plummeted over the past ...

Researchers used a new method to investigate past interbreeding with Homo sapiens that doesn't require ancient DNA. The ...

Researchers have discovered that a gene linked to congenital heart disease acts like an architect for the heart cell’s DNA.

A centromere is a specific region on a chromosome that ensures that, when a cell divides, the chromosome separates accurately so each new cell receives the correct amount of genetic material. Despite ...

We are what we are because of ancient and mysterious genetics.

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health traits. By probing regions of DNA previously linked to disease, the work has ...

DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...
