This is for many reasons. Gene mutations (point mutations) or chromosomal mutations. Deletion (a base is lost) insertion (an extra base is inserted) deletion and insertion may cause what’s called a frameshift, meaning the reading “frame” changes, changing the amino acid sequence. Changes as minor as the replacement of a single nucleotide base, which serves as the building block of dna, with a different nucleotide base can be considered mutations. There are three ways that dna can be altered when a mutation (change in dna sequence) occurs.
