Polar aging of symmetrical bacteria such as E. coli plays a role in stress responses in which of the following ways?
A) Antibiotics only affect older poles of stressed cells. B) Alternators and accelerators are better at responding to stress. C) Proteins damaged by stresses accumulate at old poles, thereby allowing new poles to continue growing. D) Newer poles are more resistant to acidity and heat. E) Newer poles produce flagella and can swim away from stress.
