What do you mean by Mutation?
Answers
At the simplest level, a mutation is a change or transformation. In biology, mutations refer to changes in chromosomes and genes, which typically manifest physically.
The effect of a mutation can depend on the region in which the sequence of genetic material has been changed. The simplest and the most harmless are substitutions of a single base pair with another, with no effect on protein sequence. At the other end are insertion or deletion mutations that lead to non-functional gene products. Mutations can also occur on a large scale, with long stretches of DNA (or RNA when it is the genetic material) being inverted, inserted, duplicated, deleted, transposed or translocated.
The result of a mutation could be harmful, beneficial, neutral or even silent.
