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.
To connect the idea of mutations back to our discussion of DNA and proteins, here are some examples of how a mutation in the DNA can lead to a change in the protein: 1) A number of nucleotides not divisible by three is either inserted into or deleted from the DNA.utation. As discussed in the introduction, mutations are changes in the genetic code that lead to different traits arising. These mutations can be passed down genetically and either be lost or become fixed.
