Around half of the genome is made up of transposable elements or 'jumping genes' that derive from ancient viral integrations. They persist in various states of decay like an old fashioned 'pull your ...

The key to dating the insertion of these elements is their LTRs — characteristic features that flank the internal region of a retrotransposon. Every family of retrotransposons has different (non-cross ...

Although many retrotransposons are found in the Drosophila genome, copia is by far the most frequently expressed one. Previous research has shown that copia predominantly targets the male germ line.

Based on previous studies in fruit flies, Andrea Schorn and Rob Martienssen of Cold Spring Harbor Laboratory thought the answer to what protects vulnerable mouse embryo genomes might lie in small RNAs ...

Genomes are hotbeds of evolutionary conflict. Perhaps nothing speaks to this idea better than the war raging between retrotransposons and their host genomes. Retrotransposons, often referred to as ...

In a recent study published in Cell, a research team led by LI Wei and ZHOU Qi from the Institute of Zoology of the Chinese Academy of Sciences has developed an innovative gene-writing technology ...

Retrotransposons are evolutionarily ancient genes that “jump” around the human genome leaving a slew of repeat nucleotide sequences in their wake. These repeats can disturb normal gene function.

Like its viral cousins, a somewhat parasitic DNA sequence called a retrotransposon has been found borrowing the cell's own machinery to achieve its goals. In a new work appearing online Wednesday in ...

Molecular, or DNA-based, markers have been increasingly important in plant breeding because of their phenotypic stability, useful polymorphism, and ease of development which permits production of high ...
