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 ...

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 ...

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 ...

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 ...

In this issue, Wu et al. show that the RecBC helicase, which is involved in repairing double-strand DNA breaks, uses one ATPase motor to drive two translocases along opposite strands of DNA—much as an ...

Transcription is the process by which DNA is converted into messenger RNA in preparation for translation into a functional product. Extrinsic agents, such as ionizing radiation or chemical mutagen and ...
