Sentences with phrase «essentially switches a gene»

Not exact matches

Epigenetic processes are essentially switches that control a gene's potentially heritable levels of protein production but without involving changes to underlying structure of a gene's DNA.

In one kind of epigenetic change, known as DNA methylation, a methyl group (a carbon atom plus three hydrogen atoms) is added to a portion of DNA; it essentially flips a gene's switch to the «off» position, shutting down the often - crucial function it performs.

MYCN and its kin are «transcription factors,» proteins that bind to DNA and influence the rate at which genetic information is used by the cell — essentially serving as brightener / dimmer switches for gene activity.

To do so it has to make special enzymes to eat that sugar and it only makes those enzymes if it is exposed to that sugar — it's a signal in a sense — and what happens is that a protein falls off of those genes and essentially the genes switch on and start making their enzymes.

But more importantly this old study (by mitochondrial membrande phospholipid fatty acids composition remodeling towards a low perodizable index PI and double bond unsaturation index DBI by genetically reduced desaturase (essentially switching perodizable polyunsaturates with monounsaturates / saturates, rendering membranes lipid peroxidation resistant / blocking hydroperoxide formation by DHA n - 3 and lowering mitochondrial DNA lesions formation by membrane lipid peroxidation chain propagation), It's true though that these effects are due to transcriptional lipid genes regulation (so the genes are the reason of this dramatic effect and this is also a gene therapy, that hit the key points) this old study showed
