Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.
Teacher: Now, understand the problem? Solve this instance: Cystic fibrosis (CF), also called mucoviscidosis, is an autosomal recessive hereditary disease of the exocrine glands. It affects the lungs, sweat glands and the digestive system. It causes chronic respiratory and digestive problems.

Cystic fibrosis is exclusively heritable as both parents must carry the recessive genes for a child to acquire the disease. At the genetic level, cystic fibrosis is most often the result of an in-frame deletion of three base pairs in the DNA. Cystic fibrosis results from the production of an abnormal form of a protein called cystic fibrosis transmembrane conductance regulator (CFTR). CFTR functions in transporting chloride ions across epithelial cells found in the lung and intestinal tract. In CF patients, CFTR does not function properly, causing accumulation of ions inside epithelial cells. Since water follows ions by osmosis, this results in water depletion and viscous mucus on the surface of alveoli. The most common CFTR protein abnormality is a mutation termed F508, which is characterized by the deletion of the DNA basepair sequence at chromosome location 7q31.1 that codes for a single amino acid, phenylalanine.
Student:
I'am doing a project and i would like to know if cystic fibrosis is a genetic diseases?
