Genes are made of deoxyribonucleic acid ( DNA ), a long molecule composed of building blocks called nucleotides.
It may seem to be a rather small-scale concern, that of neutral mutations leading to amino acid changes.
Cells have a finely tuned mechanism for correcting mutations at checkpoints during cell division, which detects most mutations.
Genes are segments of DNA located on chromosomes that contain the instructions for protein production.

This approach can be useful when it comes to a gene associated with a disease: the disease allele carries a mutation, a DNA change that compromises the protein's function.
