The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

Scientists at the Stowers Institute for Medical Research have, for the first time, identified the exact location where human chromosomes break and fuse to form Robertsonian chromosomes. The discovery ...

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, ...

Scientists have provided an explanation of how chromosomes undergo structural changes during cell differentiation. The human genome is made up of 46 chromosomes, each of which has a length of about ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

The structure of how DNA is stored in archaea makes a significant difference to how quickly it evolves, according to a new study by Indiana University researchers. The study, led by molecular ...

The central area of chromosomes, the centromere, contains DNA that has survived largely unchanged for hundreds of thousands of years, researchers at UC Davis and the Lawrence Berkeley Laboratory have ...

Hidden within fish DNA are powerful genetic twists that may explain one of nature’s biggest mysteries: how new species form so quickly. In Lake Malawi, hundreds of cichlid fish species evolved at ...
