New research illustrates how genome adapts to transposon invasion
Small, mobile sequences of DNA left over from viruses, called transposons or "jumping genes" because of their ability to move around the genome, pose a significant threat to the genetic integrity and stability of an organism. ...

A 'jumping gene's' preferred targets may influence genome evolution
The human genome shares several peculiarities with the DNA of just about every other plant and animal. Our genetic blueprint contains numerous entities known as transposons, or "jumping genes," which have the ability to move ...

Specific small RNA pathways protect germ line from transposons
Cells of higher organisms are in a constant struggle against some of their own DNA - repeated bits of DNA sequence called transposons that have infiltrated host genomes over the eons. Transposons damage the rest of the genome ...

Lab-made skin cells will aid transplantation, cancer, drug discovery research
The pigmented cells called melanocytes aren't just for making freckles and tans. Melanocytes absorb ultraviolet light, protecting the skin from the harmful effects of the sun. They also are the cells that ...

Invasion of genomic parasites triggered modern mammalian pregnancy
Genetic parasites invaded the mammalian genome more than 100 million years ago and dramatically changed the way mammals reproduce -- transforming the uterus in the ancestors of humans and other mammals from the production ...

Epigenetic changes don't last
Jean-Baptiste Lamarck would have been delighted: geneticists no longer dismiss out of hand his belief that acquired traits can be passed on to offspring. When Darwin published his book on evolution, Lamarck's ...

First lizard genome sequenced
(PhysOrg.com) -- The green anole lizard is an agile and active creature, and so are elements of its genome. This genomic agility and other new clues have emerged from the full sequencing of the lizard's genome ...
