Solution:

Gene mutation or point mutation is the result of a change in the nucleotide sequence of the DNA molecule in a particular region of the chromosome. Gene mutation occurs in the form of duplication, insertion deletion, inversion or substitution of bases. The addition or deletion of a base may change the reading frame of nucleotide sequence such type of change in nucleotide sequence is called frame-shift mutation.
