If this DNA has a mutation, the child that grows from the fertilized egg will have the mutation in each of his or her cells. Acquired (or somatic) mutations occur at some time during a personâs life and are present only in certain cells, not in every cell in the body.

An insertion mutation occurs when an extra nucleotide is added to the DNA strand during replication.nsertions and deletions are two other types of mutations that can affect cells at the gene level.
