Trinucleotide repeat expansion frequently results in the addition of extra histidine amino acids to the protein.

Homologous recombination repair requires the presence of a sister chromatid.

The term mutation refers to a heritable change in the genetic material.

Because the genetic code is degenerate, silent mutations can occur in certain bases within a codon, such as the third base, so the specific amino acid is not changed.

Breakpoints in chromosome can lead to mutant phenotypes when they occur in the middle of a gene.

The most common genotype in a population is called the mutant genotype.
