Ready, go!
Just like orchestra musicians waiting for their cue, RNA polymerase II molecules are poised at the start site of many developmentally controlled genes, waiting for the "Go!"- signal to read their part of the ...

Biologists find optimistic worms are ready for rapid recovery
For the tiny soil-dwelling nematode worm Caenorhabditis elegans, life is usually a situation of feast or famine. Researchers at the California Institute of Technology (Caltech) have found that this worm has evolved a surprisingly ...

Transcriptional elongation control takes on new dimensions
Life is complicated enough, so you can forgive the pioneers of DNA biology for glossing over transcriptional elongation control by RNA polymerase II, the quick and seemingly bulletproof penultimate step in ...

Control of gene expression: Mediator MED26 shifts an idling polymerase into high gear
Look up "transcription"—the copying of a gene's DNA into RNA intermediaries—in any old molecular biology text book, and it all seems very simple: RNA polymerase II, the enzyme that catalyzes the ...

'SKIP'-ing splicing forces tumor cells to undergo programmed cell death
When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced ...

Stop and go: How the cell deals with transcriptional roadblocks
Gene transcription is central to cell function, as it converts the information stored in the DNA into RNA molecules of defined sequence, which then program protein synthesis. The enzyme RNA polymerase II (Pol II) is responsible ...

Breaking the logjam: improving data download from outer space
(PhysOrg.com) -- Satellite systems in space keyed to detect nuclear events and environmental gasses currently face a kind of data logjam because their increasingly powerful sensors produce more information than their available ...

How plants 'feel' the temperature rise
Plants are incredibly temperature sensitive and can perceive changes of as little as one degree Celsius. Now, a report in the January 8th issue of the journal Cell, a Cell Press publication, shows how they not only 'feel' ...

Scientists discover new way in which ubiquitin modifies transcriptional machinery
During gene transcription – the process inside the nucleus of cells by which DNA, the genetic material, is copied into RNA molecules – a large, ever-changing multiprotein complex is enlisted to assist the DNA-copying enzyme ...
