Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

A subtle failure during cell division can set off dramatically different outcomes, according to new research exploring whole genome duplication. A new study finds that the way a cell fails to divide ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

Every new life begins after a genetic shuffle. When organisms make eggs or sperm, maternal and paternal chromosomes pair up and swap pieces of DNA in a process called crossing over. This exchange is ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic tangles overwhelm normal repair pathways, cells flip on a fast but error-prone ...

Cyanobacteria—ancient microbes that oxygenated Earth and made complex life possible—are still revealing surprises billions of years later. Scientists have now discovered that a molecular system once ...

Activated immune cells secrete tiny capsules bearing DNA that can enter other immune and tumor cells to stimulate the body's ...
