Latest Junk DNA Stories
The study, published today in Proceedings of the National Academy of Sciences, USA, claims to have solved this scientific riddle by analyzing the genomics of primitive living fishes such as sharks and lampreys and their spineless relatives, such as the sea squirts.
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.
