What is considered a potential use for genetically engineered members of the genus Deinococcus?Deinococcus radiodurans has been shown to have a great potential to be used in different fields of investigation. Not only has D. radiodurans been genetically modified for bioremediation applications, but also it has been discovered that it could perform a major role in biomedical research and in nanotechnology.
When all the flagella on a cell rotates in a counterclockwise?1. A bacterium with peritrichous flagella: If a bacterium has a peritrichous arrangement of flagella, counterclockwise rotation of the flagella causes them to form a single bundle that propels the bacterium in long, straight or curved runs without a change in direction.
