Cool topic you're learning about. Antibiotic resistance occurs because of the fact that bacteria change in response to the use of medicaments, such as penicillin. The problem about antibiotic resistance, an international health crisis, is that people OVERDOSE in medicaments. Antibiotics are known to kill weak and sensitive bacteria, but some resistant bacteria grow and multiplicate, since they know how the medicament works.
Therefore, I would say that bacteria that are not initially killed by the antibiotic, they go to reproduce passing the resistance on to offspring. Antibiotic resistance is a big example when it comes to natural selection.
Examples of positive and beneficial mutation:
- Antibiotic resistance by bacteria
- Almond tree gene mutation
- Humans immunity to HIV
Examples of negative and harmful mutation
- Cystic fibrosis
- Frame shift mutation
- Cancer
Examples of neutral mutation;
- Bovine and human insulin
- Silent point mutation
- Missense mutation
<h3>What are mutation?</h3>
Mutations are results from change in gene structures that leads to variations in form that can be transferred or passed down to generations. This is usually caused by alterations in the single base unit of DNAs by insertion, deletion or rearrangement of genes or chromosomes.
Positive and beneficial mutations result in retained from of adaptation like antibiotic resistance by bacteria, harmful mutation causes harm such as cancer, while neutral has little or no effect example, silent mutations.

There's a lot of compounds but one really known one is H2O because it's made out of hydrogen and oxygen atoms.
Answer: Competent cells are able to take up naked DNA, they occur naturally and can be created in the laboratory
Explanation: Competent cells are cells that can modify its genetic make up and take other DNA using transfomation. Competent cells are commonky made from e.coli because it can replicate faster, readily available for use. DNA is cleavedusing restriction enzymes making up sticky ends.
