Answer:
All the organisms has developed some methods to respond towards the changing environment. Bacteria also develops some mechanism by which they are able to tolerate the external environment.
Some bacteria respond towards environment by increasing the rate of mutation. This mutation can be accomplished as it creates the formation of oncogenes in the bacteria. The cyclins and kinases of cell cycle gets mutated that leads to the uncontrolled growth of cell bacteria. This produces an evolutionary advantage to bacteria as it allows the bacteria to grow in the hostile environment. For example: the development of resistant strain of bacteria towards a specific drug.
Every organism has devised a strategy for adapting to a changing environment. Bacteria also evolve mechanisms that allow them to tolerate the external environment and undergo mutation.
- Some bacteria respond to their surroundings by raising their mutation rate. This mutation is possible because it causes the bacteria to produce oncogenes.
- Mutations in cell cycle cyclins and kinases result in uncontrolled development of cell bacteria.
- This gives bacteria an evolutionary advantage since it permits them to grow in a hostile environment. Some bacterial strains are resistant to a specific medication.
Thus, it has become clear that environments influence not only the pace of mutation but also the mix of mutations that develop in response to various types of stress.
