How can gene therapy help cystic fibrosis patients? a) by replacing faulty genes with healthy genes
b) by introducing mucus-resistant bacteria into the lungs
c) by engineering faulty proteins
d) by creating virus-resistant genes

The correct answer is option C "by engineering faulty proteins"

Explanation:

Cystic fibrosis is brought about by transformations in the quality answerable for delivering the cystic fibrosis trans-layer conductance controller protein.

Gene therapy is a cycle wherein another, right form of the CFTR quality would be put into the cells in an individual's body. Despite the fact that the faulty duplicates of the CFTR quality would even now be there, the presence of the right duplicate would enable cells to make typical CFTR proteins.
