The below mentioned article provides a short note on gene mutation. Type of Gene Mutation: An alteration in the sequence of bases in a gene due to change, removal or insertion of one or more bases in a gene resulting in an altered gene product is called mutation. (a) Single Base Changes (Point Mutations): It may be transitions or trans-versions. [...]
