How do bacteria become resistant to drugs?
gpt
Basically, since bacteria are relatively simple organisms, with small genomes, they tend to mutate easily. Additionally, bacteria are able to divide and multiply very quickly.

As a result, as a population of bacteria grows, sub-populations of bacteria with various genetic mutations will arise, and these sub-populations will grow quickly in number. Some of these sub-populations will carry genes that protect them against the effects of antibiotics and other drugs. When the entire bacteria population is exposed to the antibiotic, bacteria without the protective gene will die, while bacteria with the gene survive, and continue to divide.

This is related to the growing problem of he increasing number of antibiotic-resistant bacteria, due to an overuse of antibiotics. As antibiotic use rises, antibiotic-resistant strains are becoming more prevalent. Soon it will be difficult to combat these new strains of bacteria.
