Explanation:

Cystic fibrosis results when patients inherit two copies of a recessive CFTR gene.  The recessive CFTR genes produce a protein which causes mucus to build up in parts of the body. Having just one dominant CFTR gene allows the body to produce a normal protein. Individuals with one dominant CFTR gene have no cystic fibrosis symptoms. Which question would BEST help researchers identify a potential treatment for cystic fibrosis?

Question 16 options:

d. Can DNA fingerprinting identify which individuals have cystic fibrosis and which do not?

a. Can recessive CFTR genes recombine with bacterial DNA to be cloned?

b. Can a dominant CFTR gene be inserted in patients’ cells using a virus?

c. Can stem cells be used to change the recessive CFTR genes into dominant CFTR genes in patients’ cells?
