Not exact matches

Where is the clear line in a progression from (1) using animal insulin to treat diabetes, to (2) using gene remodeling techniques to grow insulin in a host bacterium that will reproduce rapidly and from which a plentiful supply of insulin can be harvested, to (3) genetic surgery to replace the defective gene in a person diagnosed as diabetic, to (4) genetic surgery immediately after fertilization in order to replace the defective gene and alter the germ cells which would otherwise have transmitted the disease to one's offspring?

In genetic modification (or engineering) of food plants, scientists remove one or more genes from the DNA of another organism, such as a bacterium, virus, or other plant or animal, and «recombine» them into the DNA of the plant they want to alter.

It was unlikely that all 24 genes would be altered simultaneously in any one bacterium, so the cycle was repeated over and over to increase the proportion of cells with mutations in all 24 genes.

«They've done this by altering their genetic make - up; transferring drug - resistant genes between one another; and creating biofilms, which are multicellular communities where bacteria can be a thousand-fold more resistant to antibiotics.»

This new gene expression data therefore provides additional evidence that the altered behavior of bacteria in space results from decreased gravity driving reduced extracellular transport of molecules.

In the Lyme bacteria's genome, the VlsE gene is preceded by «cassettes» which are normally not expressed, or made into individual proteins, but can recombine with VlsE to alter the expressed protein and thus present a novel challenge to a host's immune defenses.

Although bacteria have a seemingly limitless capacity to alter their genes by swapping bits of DNA between strains, this mechanism doesn't seem enough to account for the swift pace of change and the high variability of E. coli and other strains.Thomas Cebula of the U.S. Food and Drug Administration (FDA) wondered if this rapid evolution is being driven by microbes capable of much faster - than - normal variation.

The agency decided the mushroom was not subject to regulations on genetically modified organisms (GMOs) because, unlike previous genetic engineering techniques, gene editing does not insert foreign DNA from viruses or bacteria to alter a plant's function.

«But we want to do everything we can — whether it's changing how we treat infections in medical clinics or altering the way we manage the environments where bacteria grow — to keep the odds stacked against sharing of these genes.»

Bacteria can acquire resistance by getting a copy of a gene encoding an altered protein or an enzyme like beta lactamase from other bacteria, even from those of a different Bacteria can acquire resistance by getting a copy of a gene encoding an altered protein or an enzyme like beta lactamase from other bacteria, even from those of a different bacteria, even from those of a different species.

CRISPR, a new gene editing technology that is derived from the immune systems of certain bacteria, allows researchers to alter genes with unprecedented accuracy.

In fact, the beneficial bacteria strains in milk kefir actually repopulate the digestive tract, whereas the cultures added to yogurt work more behind the scenes to positively alter gene expression and reduce inflammation.

Diet - related nutrogenic diseases can be aggravated when various food ingredients alter the health - promoting population of bacteria in the digestive system, the «microbiome» or «garden of the guts,» and when a particular breed or individual genome has gene - related processes and reactions to food ingredients that cause or aggravate illness.

Like the bacteria that cause gonorrhea, members of T. pallidum have multiple copies of the gene coding for the proteins that allow them to adhere to human cells — perhaps, as in the case of gonorrhea, these genes allow T. pallidum to alter their surface proteins in order to escape recognition by the immune system.
