Gene Mutations affect a single gene by changing its base sequence, resulting in an incorrect, or nonfunctional, protein being made. (a) A SUBSTITUTION mutation, occurs where one nucleotide base is replaced by another. These are often called "point mutations", because a single base is changed, at one point in the gene. 1.

A frameshift mutation is a mutation from when you add and extra AT GC (U) into the gene sequence. It changes the sequence and how it gets read. The third mutation you explored is a special kind of point mutation called a SILENT mutation. Explain what this means. A silent mutation is when an AT GC (U) is changed but it the sequence doesn't change.

A genetic sequence change is referred to as a mutation. 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. Meanwhile, larger mutations can have an impact on a chromosome's several genes.
