Researchers find genetic defences of bacteria don't aid antibiotic resistance

When bacteria are exposed to antibiotics, they alter the expression of a number of genes within their genome. One of these responses, known as the SOS response, results in an increase in the rate of DNA mutation. Given that DNA mutation is a fundamental trait of evolution, many people have speculated that the stimulation of this response helps contribute to the increased resistance to antibiotics in bacteria over time.
