Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...

The Pol-theta enzyme (blue) joins two parts of a broken DNA strand (yellow). This process is mutagenic and can give rise to cancer. LA JOLLA, CA—DNA repair proteins act like the body’s editors, ...

A common hallmark of viral genome replication is a high mutation rate, which can aid in their ability to evade new treatments and acquire resistance to once-effective antiviral medications. Now, a new ...

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...
