Question:

Solution:

The gene that encodes the CFTR protein is located on chromosome 7.

The most common disease-causing mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene is the out-of-frame deletion of 3 nucleotides (CTT). This mutation leads to the loss of phenylalanine-508 and a silent codon change for isoleucine-507.

Then, the correct answer is:

Three nucleotides in the CFTR gene are delated on chromosome 7.
