Unravelling the function of small RNAs

Small non-coding RNAs (ncRNAs) play a hitherto unrecognised role in regulation of gene expression. To broaden knowledge on the function and evolution of these molecules, a EU project investigated various classes of regulatory ...

Scientists use light to 'tag and track' genetic processes

(Phys.org) -- In a new study, UT Dallas researchers outline how they used fluorescent molecules to "tag" DNA and monitor a process called DNA looping, a natural biological mechanism involved in rearranging genetic material ...

The path from stem cell to maturity

Regulation of gene expression is essential to make sure cell maturation occurs as it should. European research is taking an integrated perspective on how selected steps in liver and blood cell differentiation can be modulated.

Molecular controller switches off genetic material

(Phys.org) -- Genetic material has many inactive sections that are of major importance for cell identity and genome stability. The HP1 protein takes on key functions in shutting down such genomic sequences. In the latest ...

New details about gene regulation explained

(Phys.org) -- When genetic information is read from the genetic blueprint DNA, RNA polymerase II translates it into RNA molecules. The C-terminal domain, abbreviated as CTD, is an important area of the polymerase molecule. ...

History is key factor in plant disease, study finds

(Phys.org) -- The virulence of plant-borne diseases depends on not just the particular strain of a pathogen, but on where the pathogen has been before landing in its host, according to a new study from researchers at the ...

Scientists find a key to growth differences between species

The tiny, little-noticed jewel wasp may provide some answers as to how different species differ in size and shape. And that could lead to a better understanding of cell growth regulation, as well as the underlying causes ...
