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 single amino acid (phenylalanine) at position 508. This mutation is referred to as ΔF508.
