Sentences with phrase «from jumping gene»

Some proteins recycled from jumping gene parts have also proved extremely useful, especially for the immune system.

The scientists were able to see the piRNA bind to a jumping gene messenger RNA in the cell's cytoplasm and to the PIWI protein, which then cut the first section from the jumping gene mRNA to silence it.

In germline cells PIWI proteins silence the RNA from jumping genes by cutting them in sequences of ~ 30 nucleotides that will become piRNAs.

They are also able to guide PIWI proteins to the jumping gene in the nucleus, which the PIWI protein silences, preventing it from creating more jumping gene RNA.

Using bioinformatics tools to identify and map out specific components and regulatory interconnections, the study team found highly dynamic activities during CD8 + T cell responses: a distinct repertoire of super enhancers — groups of enhancers that interact with promoters to drive gene transcription, new groups of enhancers that jump into activity only in the memory cell stage, and extensive re-wiring of regulatory circuits from one cell stage to another.

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.

The sequence had to be easy to isolate but couldn't jump inexplicably from one organism to another, as some genes do.

The protocol is supposed to protect countries from unwittingly importing transgenics that could harm their environment — for example, if a gene inserted in a crop to make it resistant to herbicides were to jump into a related weed.

The science of genetics is built on Gregor Mendel's work on peas; Barbara McClintock discovered transposable elements — «jumping genes» — while working on maize; the science of «RNA interference» and its potential therapeutic applications derives from early studies of cosuppression in transgenic purple petunias.

The researchers analyzed DNA sequences known as transposons, or «jumping genes,» which can jump from one part of the genome to another, often duplicating themselves in the process.

Of the locations sampled in the study, resistance genes that are most likely to be mobile and able to jump from one bacterial strain to another were found in the highest numbers in the chicken coops of villagers in El Salvador and in the outgoing «gray» water from the sewage treatment plant outside Lima.

Transposons, sometimes called «jumping genes,» are a piece of DNA that can move from one place to another in the cell's chromosomes.
