Question
Microbes acquire resistance to antibiotics through different processes that include random what and sexual reproduction.
Solution
Microbes acquire resistance to antibiotics through different processes that include random mutation and horizontal gene transfer, which is often likened to sexual reproduction in bacteria.
-
Random Mutation: This is a spontaneous change in the organism's genetic material. When bacteria are exposed to an antibiotic, those with mutations that allow them to survive will reproduce, passing these beneficial traits to their offspring. Over time, a population of antibiotic-resistant bacteria can emerge.
-
Horizontal Gene Transfer: This is akin to sexual reproduction in bacteria. It involves the transfer of genetic material between two bacteria, which are not parent and offspring. This can occur through three main methods: transformation (uptake of genetic material from the environment), conjugation (direct transfer of genetic material from one bacterium to another), and transduction (transfer of genetic material from one bacterium to another via a virus). This process can spread antibiotic resistance genes across different species of bacteria.

Describe what antibiotic resistance is and explain how it develops in a population of bacteria.
In this experiment, the bacteria stopped spreading when they reached an area with a higher concentration of antibiotics. Remember that there are millions of bacteria and that they reproduce very quickly. After a while, a new "mutant" population can be seen fanning out from a single point.Using the concepts from this lesson, explain how this new population with higher antibiotic resistance arises.
