In short, DNA fingerprinting involves the generation of a set of distinct DNA fragments from a single DNA sample; these fragments are then used as a source of genotypic information. A wide range ...

This fragment is radioactively labeled on one end and then incubated in vitro both with and without the transcription factor of interest. Next, the DNA is treated with a nuclease, such as DNAse I ...

microbiologists have known for decades that bacteria may activate or deactivate genes by flipping little portions of their DNA, but as far as the researchers are aware, those tumbling fragments ...
