Genetic mutations are really important for how bacteria become resistant to antibiotics. It's actually pretty interesting! Let’s break it down into simpler parts:
What are Mutations?
Genetic mutations are random changes in the DNA of bacteria. They can happen when bacteria divide or because of things in their environment. Not all mutations are bad; some can help bacteria survive better.
Understanding Antibiotic Resistance:
When bacteria face antibiotics, some of them might have mutations that help them live. For example, a mutation can change a part of the bacteria that antibiotics attack, making the medicine useless against them.
Selection Pressure:
Using antibiotics puts pressure on bacteria. This pressure means that only the bacteria with mutations that keep them safe can survive. Over time, these stronger bacteria will multiply, and they pass their skills on to their offspring.
Sharing Resistance:
Bacteria can also share their resistance abilities with each other. They do this through a process called horizontal gene transfer. This helps resistance spread even faster.
In short, genetic mutations help bacteria survive against antibiotics. This is a real-life example of how evolution works!
