About Genetic Mutation
Gene mutation is any change in the genetic information of any organism. These changes occur at many different levels, and they can have widely differing consequences. Mutations may be caused due to effects of physical agents and chemical agents. Mainly there are different types of mutations which include deletions, insertions, point mutations, substitutions, missense mutation, nonsense mutations etc. Most disease-causing gene mutations are uncommon in the general population. However, other genetic changes occur more frequently.
