Answer: An example of point mutation on the gene is TGC CG.
Explanation: Mutation is a permanent alteration in the nucleotide sequence of a DNA. Point mutation is a type of mutation in which there is a change in only one nucleotide molecule in a DNA sequence. A point mutation can occur at any point in the nucleotide sequence of a DNA and can be as a result of replacement of one nucleotide molecule by another. For example, in the the sequence TAC CG, any of the nucleotides can be replaced by another nucleotide such as in TGC CG, Adenine is replaced by Guanine.
