To get the full story you need to know the motifs
Genome sequencing alone provides researchers with only limited information on the organism works because it neither reveals how the system is regulated nor does it indicate the role of each specific DNA sequence or RNA transcript. ...

Study uncovers how DNA unfolds for transcription
(PhysOrg.com) -- The human genome contains some 3 billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would ...

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 ...

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 ...

Rethinking reprogramming: A new way to make stem cells
A paper published by Cell Press in the April 8th issue of the journal Cell Stem Cell reveals a new and more efficient method for reprogramming adult mouse and human cells into an embryonic stem cell-like state and could ...

Identifying molecular guardian of cell's RNA
When most genes are transcribed, the nascent RNAs they produce are not quite ready to be translated into proteins - they have to be processed first. One of those processes is called splicing, a mechanism by ...

'Runaway' development implicated in loss of function of the aging brain
The brain undergoes rapid growth and development in the early years of life and then degenerates as we progress into old age, yet little is known about the biological processes that distinguish brain development and aging. ...

UM scientists demonstrate role of RNA polymerase in gene transcription
In all organisms, RNA synthesis is carried out by proteins - known as RNA polymerases (RNAPs) - that transcribe the genetic information from DNA in a highly-regulated, multi-stage process. RNAP is the key enzyme involved ...

The 3-dimensional transcription film
Gene expression takes place in two stages: the transcription of DNA to RNA by an enzyme called RNA polymerase, followed by the translation of this RNA into proteins, whose behaviour affects the characteristics of each individual.
