Question

E. coli is a species of bacteria that causes many different infections in humans. certain e. coli strains have developed resistance to antibiotics, making infections with these strains difficult to treat. how do bacteria such as e. coli, which reproduce asexually, gain new traits such as antibiotic resistance?

Answer 1

By mutating their DNA in response to environmental conditions to gain beneficial traits,  reproduce asexually, gain new traits such as antibiotic resistance.

• Antibiotic resistance in bacteria denotes the bacteria's incapacity to be treated by an antibiotic, which means the antibiotic's effectiveness against the bacteria is either abolished or diminished.

What environmental factors could cause DNA to mutate?

If mistakes are made and not fixed right away. Additionally, exposure to environmental elements including smoking, sunshine, and radiation can result in mutations.

Which type of mutation depend on the condition of the environment?

Somatic mutagenesis

• Therefore, a large portion of an organism may have the same mutation.
• These kinds of mutations, which can result in diseases like cancer, are typically brought on by environmental factors like ultraviolet radiation or any exposure to certain dangerous substances.

What is a mutation that is beneficial?

• A type of mutation known as a beneficial mutation affects an organism in a favorable way.
• These mutations are uncommon but important.
