Latest RNA polymerase I Stories
New research has shown that a protein does something that scientists once thought impossible: It unfolds itself and refolds into a completely new shape.
Successful gene expression requires the concerted action of a host of regulatory factors.
Look up "transcription"â€”the copying of a gene's DNA into RNA intermediariesâ€”in any old molecular biology text book, and it all seems very simple: RNA polymerase II, the enzyme that catalyzes the reaction, assembles at the start site and starts motoring down the strand, cranking out the RNA ribbon used to construct proteins.
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 DNA genomes of organisms whose cells possess nuclei are packaged in a highly characteristic fashion.
Plants are incredibly temperature sensitive and can perceive changes of as little as one degree Celsius.
All cells perform certain basic functions. Each must selectively transcribe parts of the DNA that makes up its genome into RNAs that specify the structure of proteins.
The body's nanomachines that read our genes don't run as smoothly as previously thought, according to a new study by University of California, Berkeley, scientists.
