Answer the following question and explain your answer If there is a family history of CF (cystic fibrosis), couples may have themselves tested for carrying a mutation in the CFTR gene to learn about a potential risk for their offspring to have CF. Unfortunately, the fact that there are so many different mutations (approx. 1800 known mutations) makes it very difficult to develop diagnostic tests that allows the identification of all mutations. One method employed in the diagnostics of CF is PCR .Would you be able to recognize the following mutations with a PCR-based diagnostic test? a) A premature STOP codon b) The deltaF508 mutation
