When it comes to gene transcription, random pauses aren’t quite so random, study finds
... team found that a molecule of RNAP makes frequent pauses at specific sites along the DNA double helix. This...en for no apparent reason it appears to stop. Some pauses we've already figured out.

...hose maneuvers in a discrete stepwise fashion with pauses in between. This stepwise approach enabled the researchers to distinguish whether the lateral PFC neurons were active during planning the movements or planning the events that would result from those movements.

...ns are rather slow because the follower frequently pauses to look round for landmarks so that it can learn the route. Only when the follower has done this does it tap on the hind legs and abdomen of the leader to let it know that the tandem run can proceed. The researchers' detailed analysis of the moveme......ress difficult. Unable to continue copying, RNAPII pauses and sometimes grinds to a halt. Exposure to sunlight causes decreased transcription when ultraviolet-induced DNA damage blocks RNAPII. Transcription-coupled repair normally removes the blocking damage and allows transcription to recover; in Cockayne...
