mumans, the CFTR gene is responsible for a protein that regulates the components of sweat, digestive fluids, and mucus. Individuals with a mutated version of this gene develop cystic fibre
me following research questions would provide the best data for clarifying the role of DNA in the development of this disease?
What environmental factors stimulate or slow the production of sweat, digestive fluids, and mucus?
is cystic fibrosis present in individuals who have a normal, non-mutated copy of the CFTR gene?
Are the components of sweat, digestive fluids, and mucus significantly different in individuals with cystic fibrosis?
What is the current rate of the development of cystic fibrosis in the human population and has this changed over time?
