Sentences with phrase «called noncoding»

And this so - called noncoding DNA plays a role in some diseases, studies have shown.

Once dismissed as «junk DNA,» researchers have found that some of these so - called noncoding regions are shared among mammals, suggesting they play an important function.

Now, a new study probing so - called noncoding DNA has found that alterations in regions that regulate gene activity may also contribute to autism.

«People used to call the noncoding regions junk DNA, but I see it as a jungle that has not been explored,» said Christopher Gregg, Ph.D., assistant professor in Neurobiology and Anatomy at U of U Health.

Not exact matches

The shared patterns of gene expression in the limbs and phallus are generated in part by a common set of noncoding DNA, also called «elements» or «enhancers,» which act to control gene expression in both of these structures, argues a study published October 1 in Developmental Cell.

Assessing the influence of individual DNA base changes is particularly difficult in noncoding regions, so they instead identified bigger alterations, so - called structural variants, in which large sequences of DNA are inverted, duplicated, or deleted.

In a series of elaborate experiments researchers from Harvard Medical School and Brigham and Women's Hospital discovered that mouse poop is chock full of tiny, noncoding RNAs called microRNAs from their gastrointestinal (GI) tracts and that these biomolecules appear to shape and regulate the microbiome.

Noncoding DNA includes stretches called enhancers, short sequences that help control a target gene.

One gene set that stood out involved components of the spliceosome, the molecular complex that helps prepare messenger RNA (mRNA) transcripts for protein production by removing noncoding segments called introns.

One of the gene's molecular targets, for example, is a microRNA (a small noncoding RNA molecule) called let7, which in turn regulates hundreds of other genes, so the effects of Lin28a can set off a complex array of regulatory interactions.

That diet, a mixture of pollen and honey called «beebread,» is shot through with a special kind of microRNA (miRNA), noncoding RNA molecules that help regulate gene expression.
