Explanation:
Trinucleotide repeat is a genetic mutation where a crack of three nucleotides is repeated, next to each other, so many times that it leaves the DNA molecule unstable.
This mutation is capable of causing errors in the reading of DNA, which results in disorders and syndromes in the affected organism.
The three strands of DNA shown above show this mutation.
