Making the world better, one answer at a time. A point mutation, or single base substitution, is a type of mutation that causes the replacement of a single base nucleotide with another nucleotide of the genetic material, DNA or RNA.One can categorize point mutations as follows: Transition mutations are about an order of magnitude more common than transversions.aking the world better, one answer at a time.

One can categorize point mutations as follows:
Examples of spontaneous mutations include point mutations and frameshift mutations. Point mutations are the result of incorrect base pairings during cell division. If the amino acid code (triplet) is not altered by the change in bases, the point mutation is said to be synonymous. The resulting protein is not altered.
