Assume that you are working with a mutant, nutritionally deficient strain of escherichia coli and that you isolate "revertants," which are nutritional-normal. describe, at the molecular level, two possible causes for the "reversion to wild type."

Mutation may be defined as the sudden heritable change in the genetic sequence of the organism. The mutation can cause the characteristics phenotype in the individual.

Two ways by which the reversion to wild type occur are true reversion and suppression mutation. The true reversion process involves the precision of the correction of the original mutation. The suppression intragenic or intergenic  mutation introduce the changes in the mutant gene and compensate for the wild type product.
