Scientists
have coaxed the model bacterium Escherichia
coli to resist ionizing radiation and, in the process, reveal the genetic
mechanisms that make the feat possible. The study provides evidence that just a
handful of genetic mutations give E. coli
the capacity to withstand doses of radiation.
The
findings are important because they have implications for better understanding
how organisms can resist radiation damage to cells and repair damaged DNA.
For
further details, refer to the following paper:
