Question

Which type of mutation causes cystic fibrosis?(1 point) Responses insertion insertion substitution substitution deletion deletion silent

Answer 1

Cystic fibrosis is primarily caused by a deletion mutation. Specifically, the most common mutation associated with cystic fibrosis is a deletion of three nucleotides in the CFTR gene, which results in the loss of a phenylalanine amino acid at position 508 (ΔF508). Therefore, the correct response is "deletion."
