Transposable elements, or "jumping genes", were first identified by Barbara McClintock more than 50 years ago. Why are transposons so common in eukaryotes, and exactly what do they do? In addition ...

Adverse genetic mutations can cause harm and are due to various circumstances. 'Jumping genes' are one cause of mutations, but cells try and combat them with a specialized RNA called piRNA.

A team at the University of Tokyo has developed a system to control and accelerate the evolution of changes in bacterial genome structure, targeting small "jumping genes," or DNA sequences known ...

Transposable elements (TEs), the so-called "jumping genes," are seldom studied due to computational difficulties. Nonetheless, in recent years, there has been an increase in studies focused on the ...

But Chiappinelli, then a postdoctoral fellow in Stephen Baylin’s lab at Johns Hopkins University, also saw an upregulation in genes involved in innate immunity ... these elements are mere relics of ...

For decades, scientists dismissed transposable elements, also known as transposons or “jumping genes”, as useless “junk DNA”. But are they really? The early speculations of both McClintock ...

TEs, also called transposons or jumping genes, are often cast in a negative evolutionary light. And there is a reason for that: when these sequences insert themselves into new places in the genome, ...

A fungus that infects salamanders contains multiple copies of the same “jumping genes”, scientists have discovered. Jumping genes, called transposons, can “copy and paste” themselves and ...

Evidence from prior studies suggests that LINE jumping genes are tightly regulated by the brain, but are still important for learning and for memory formation in the hippocampus. You may like ...

Nearly all these inserted elements have been silenced by our cells' defense mechanisms over time, but a few, nicknamed "jumping genes," can still move around the human genome like viruses.

“In the search for these higher-level gene regulation mechanisms, we came across an enrichment of so-called transposons or jumping genes in epigenetically accessible DNA regions,” describes Dr. Lisa ...

Researchers at the Leibniz Institute for Immunotherapy (LIT) describe a new type of regulation of immune cells by so-called "jumping genes." The immune system defends the body against invading ...
