It's long been assumed that as cells divide in the human body, the genome is faithfully replicated in the resulting daughter cells. While errors are known to arise, there is machinery in the cell that ...

A deeper understanding of how DNA changes over generations helps scientists learn why people differ and how diseases develop. Until recently, many fast-changing parts of the human genome remained ...

Scientists have identified how specific genetic changes function in cells to influence disease risk and other human health ...

The majority of DNA in one’s body does not encode for any protein. In a Feb. 25 lecture, Rachel Mueller, Colorado State University biology professor, addressed questions surrounding junk DNA, ...

How much of our genome really matters? Some argue that because most of our DNA is active, it must be doing something important. Others say even random DNA would be highly active. This has now been put ...

Following a double-strand DNA break, an enzyme called PARP1 helps hold the two strands together —like superglue— and creates a safe zone for other proteins to come repair the damage. We don’t exactly ...
