Latest Mobile genetic elements Stories
By Ehrenberg, Rachel Genes & Cells 'Junk DNA' helps to distinguish people from other primates Genes alone don't make the man - after all, humans and chimps share roughly 98 percent of their DNA.
Promega Corporation announces a new plasmid isolation system that simplifies and speeds the preparation of plasmid DNA. The Promega PureYield(TM) Plasmid Miniprep System allows researchers to purify plasmid DNA in less than 10 minutes from 600microl to 3 ml of culture with fewer steps.
Howard Hughes Medical Institute researchers have harnessed a mobile gene from the cabbage looper moth and modified it for routine use to determine the function of genes in mice and other vertebrates. If the new tool works as they expect, it will speed understanding of genes involved in human biology and disease and accelerate the search for effective new therapies.
A collaborative project between American and Chinese researchers developed a way to study the function of genes in mice and man by using a moveable genetic element from moths, according to a report in the journal Cell.
In a paper published in this week's Proceedings of the National Academy of Sciences (PNAS), MBL scientists Irina R. Arkhipova and Matthew Meselson provide evidence that suggests bdelloid rotifers--which probably gave up sex at least 50 million years ago but have still evolved into 370 species--handle DNA transposons more efficiently than other asexual species.
Researchers at the University of Minnesota Cancer Center and the National Cancer Institute have discovered a new method that could accelerate the way cancer-causing genes are found and could lead to a more accurate identification of the genes, according to two studies in the July 14, 2005, issue of Nature.
Brains are marvels of diversity: no two look the same -- not even those of otherwise identical twins. Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells.
