Understand that mutations refer to changes in the genetic material, which is DNA in most organisms.
Recall that DNA is composed of nucleotides, which are the basic building blocks consisting of a sugar, phosphate group, and nitrogenous base.
Recognize that a mutation initially involves an alteration in the sequence of these nucleotides, such as a substitution, insertion, or deletion.
Note that changes in the amino acid sequence of a protein or other cellular components occur downstream as a consequence of mutations in the DNA sequence.
Therefore, the mutation starts at the level of the nucleotide sequence of DNA before affecting other molecules like proteins or cellular structures.
