Question

disease is one class of genetic diseases called 'triplet repeat disorders'. These disorders occur when a repeat of three nucleotides gets amplified by errors during DNA replication. People with a small number of repeats (10-20) don't get the disease while people with larger numbers of repeats (80-200) do get the disease.
