| Cystic fibrosis is one of the most common

| |
| | and the normal secretions of the organs
|
| produces a protein called cystic fibrosis
| |
| | become thick. Mucus in the exocrine
|
| transmembrane regulator. Mutation in the
| |
| | glands becomes thick and sticky. This
|
| DNA level of chromosome 7 leads to the
| |
| | results in blocks in the pancreas, lungs,
|
| absence of this protein which leads to
| |
| | liver and other glands. This block leads
