Answer:
The correct answer is option E. "DNA in both daughter cells would be radioactive".
Explanation:
Radioactive thymidine incorporation has irremediable effects in thymine and cytosine in bacteria such as E. coli. Although there are some reports of recovery of E. coli from UV-irradiation DNA damage, the presence of radioactive bases such as thymine is often irremediable. Therefore, after a dividing culture of E. coli exposed to radioactive thymine divides, DNA in both daughter cells would be radioactive.
The answer would be B tropic level
