A woman trying to get pregnant has a sister whose child has an autosomal recessive disease
characterized by dysfunction of mucus-secreting cells. As a result, this child has abnormally
thick mucus that tends to precipitate into dense plugs that obstruct the pancreatic ducts, bronchi,
and bronchioles, as well as the bile ducts. Which of the following tests could be performed to
determine if this woman and her husband are carriers of this disease?
A. Northern blot
B. PCR and sequencing
C. Southern blot
D. Western blot
