Double-strand breaks in DNA are potentially lethal to a cell if not repaired. They arise in several ways, including DNA damage from ionizing radiation and as a result of single-strand nicks that ...

A DNA sequence that acts as a throttle to control the rate at which an enzyme moves along the DNA has been observed by researchers at UC Davis. By controlling the activity of the RecBCD helicase ...

Breaks in our genetic code termed “DNA double-strand breaks” create cellular stress and cell death if not rapidly repaired. Environmental mutagens including UV light can cause DNA breaks, and these ...

RecBCD, an enzyme that unwinds the DNA double helix so that it can be copied or repaired, is powered by two motor units that run in opposite directions, according to a report by UC Davis researchers ...

The DNA of all organisms, be it bacteria or humans, is constantly bombarded with damage either by environmental mutagens such as the exposure to UV light or because of erroneous replication. The ...

Experiments by biochemists at the University of California, Davis show for the first time that a law of physics, the ergodic theorem, can be demonstrated by a collection of individual protein ...
