<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.
