... elements so successful? Some think that they are simply "junk" that, much like viruses, they can make lots of copies but do little to help the host. There is mounting evidence, however, that TEs help organisms evolve by making it easier to generate the sort of genetic novelty that is necessary for them t...UCI scientists successfully target key HIV protein; breakthrough may lead to new drug therapies
