Many different types of mutations can occur within the body. Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene. One mutation in the CFTR gene that leads to cystic fibrosis causes translation
to end earlier in the gene sequence. Which type of mutation causes this translation error that leads to cystic fibrosis?
silent
missense
nonsense
deletion

Nonsense

Explanation:

Nonsense mutations introduce a premature stop codon into the sequence. A stop codon is one of the following sequences: UAG, UAA, or UGA.

If this sequence is introduced earlier than it should be in the gene, for example by a substitution, deletion, or insertion of a nucleotide, then the protein synthesis machinery stops translation in the middle of the protein, not at the end as it should be.

This means that an incomplete protein is synthesized.
