alleryWhich highly radiation-resistant bacterium has been genetically modified to absorb radiations from radioactive debris?
AVibrio cholerae
BBacillus thuringiensis
CRhizobium
DDeinococcus radiodurans
Answer & Solution
Correct answer: D. Deinococcus radiodurans
1. The organism needed must survive intense radiation.
2. Deinococcus radiodurans is highly radiation resistant and is genetically modified to absorb radiation from radioactive debris.
3. Bacillus thuringiensis is used for Bt crops, Rhizobium is a biofertiliser and Vibrio cholerae is a cholera target, none meant for radiation cleanup.
