Question

What kind of new therapies are scientists working on to treat cystic fibrosis?

Select all that apply.

gene therapies to fix the CFTR gene
injections to add water directly to the mucus
inhalers to deliver CFTR to the cells
gene editing to remove the CFTR protein

Answer 1

The correct answer is B make cells produce a functional CFTR protein.

Explanation:

Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.

If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.

Answer 2

A. gene therapies to fix the CFTR gene

C. inhalers to deliver CFTR to the cells
