Sentences with phrase «called jumping genes»

Their analysis includes so - called jumping genes that can move around the same genome, sometimes causing damage to individual genes or enabling antibiotic resistance.

Informally called jumping genes, these bits of DNA can replicate and insert themselves into other regions of the genome, where they either lie silent, doing nothing; start churning out their own genetic products; or alter the activity of their neighboring genes.

«The most frequent way is the transfer via mobile genetic elements such as plasmids, or via transposons, the so - called jumping genes,» explains Friederike Hilbert, scientist at the Institute of Meat Hygiene at the Vetmeduni Vienna.

Not exact matches

Jumping genes, also called transposons, are often given names that reflect their mobility — Gulliver, Mariner, Vagabond.

They found that the strain had acquired the gene for phospholipase A2, called SlaA, in the mid-1980s, which suggested that SlaA was responsible for the jump in virulence.

They bond to proteins called PIWI and guide them to the messenger RNA produced by the jumping genes, which the PIWI protein then destroys.

A European team of scientists has discovered how the cells produce tiny pieces of RNA — called piRNA — that identify and silence «jumping genes» or transposons: genes that are able to change their position within the genome and therefore alter or disrupt the genetic code.

Jarvis told me she knocked out a Hox gene called Abd - B in this one — the embryo will grow jumping legs where it should have swimming legs, and forward walking legs instead of anchor legs.

The repeats are mobile elements called transposons, also known as jumping genes, which can trigger mutations in the genes around them and lead to genetic disorders.

In brain cells, Alu has repeatedly jumped into DNA associated with a gene called TOMM40.

CRE are Gram - negative bacteria that frequently express a gene that codes for carbapenemase — an enzyme that breaks down carbapenem and other antibiotics — and that is located on «mobile genetic elements» called plasmids, which can jump from one bacterium to another.

Recent research by neuroscientist Fred Gage and colleagues at the University of California (UC), San Diego, has shown that one of the most common types of jumping gene in people, called L1, is particularly abundant in human stem cells in the brain that ultimately differentiate into neurons and plays an important role in regulating neuronal development and proliferation.
