Question

What is the cause and effect of cystic fibrosis? What is the ion most associated with this disease?

a) Cause: Mutation in the CFTR gene; Effect: Increased mucus production; Ion: Sodium
b) Cause: Mutation in the CFTR gene; Effect: Decreased mucus production; Ion: Chloride
c) Cause: Mutation in the BRCA1 gene; Effect: Increased mucus production; Ion: Calcium
d) Cause: Mutation in the BRCA2 gene; Effect: Decreased mucus production; Ion: Potassium

Answer 1

Cystic fibrosis is a genetic disease caused by a mutation in the CFTR gene, resulting in the production of thick and sticky mucus in various organs.

Step-by-step explanation:

Cystic fibrosis is a genetic noninfectious disease caused by a mutation in the CFTR gene. The mutation leads to the production of a faulty protein, which impairs the transport of chloride ions out of cells. This results in the production of abnormally thick and sticky mucus in the organs, such as the lungs, pancreas, and intestines.
