Knocking genes out of action allows researchers to learn what genes do by seeing what goes wrong without them. University of Utah biologists pioneered the field. Mario Capecchi won a Nobel Prize for developing knockout mice. ...

The genome is not a fixed code but flexible. It allows changes in the genes. Transposons, however, so-called jumping genes, interpret this flexibility in a much freer way than "normal" genes. They reproduce in the genome ...

How can fungi that only multiply vegetatively adapt so quickly to in the immune system of plants? The answer appears to lie in the way how the DNA of an asexual pathogen can rapidly adapt due to 'jumping genes' and also genetic ...

Over a decade after sequencing the human genome, it has now become clear that the genome is not mostly 'junk' as previously thought. In fact, the ENCODE project consortium of dozens of labs and petabytes of data have determined ...
