Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

Enzymes, which are crucial to controlling how cells replicate in the human body, could be the very ingredient that encourages DNA to spontaneously mutate -- causing potentially permanent genetic ...

Researchers at Johns Hopkins Medicine, in collaboration with researchers at the National Institutes of Health, report that two new studies in mice with a humanized immune system and human cell lines ...

A protein that prepares DNA for replication also prevents the replication process from running out of control, according to a new study by Weill Cornell Medicine researchers. The work, published Jan.

In nature, evolution takes years to sculpt new traits. In the lab, scientists hope to achieve this feat much faster: Being able to evolve proteins with enhanced or novel functions has important ...

Since HIV’s discovery in the 1980s, scientists have come a long way in understanding the different steps required for its assembly and maturation. Researchers knew, for instance, that HIV wraps its ...
