Question 11/03
IMMORTAL BACTERIA
Bacteria are almost immortal. (Apollo 12 crew recovered bacteria
that were accidentally brought to the Moon 3 years earlier by
Surveyor probe, and those bacteria were revived. There are claims
of revival of 30 million year-old bacteria.) How long will it take
for the cosmic radiation to destroy the DNA of a bacterium.
This question was inspired by "Fermi question" site that can be found
here.
