How does Cystic Fibrosis affect the gas exchange system, digestive system and reproductive system? Every cell in the body needs different proteins for specific functions. DNA determines the structure of the protein. If DNA or RNA changes the structure of the protein, used for a particular function, due to wrong transcription or translation of protein synthesis, mutations occur. These mutations can lead to genetics disorders or genetic diseases. Cystic Fibrosis is one of the most common genetic diseases caused due to an abnormality in Cystic Fibrosis Transmembrane Regulatory (CFTR) protein. CFTR controls the osmosis of water and salts in and out of mucus (indirectly). Fault in CFTR protein results in making the mucus viscous. This thickened mucus can affect many body systems including the three main body systems: * Gas Exchange System (by affecting lungs) * Digestive System (by affecting pancreas, liver, gall bladder and intestines) * Reproductive System (by clogging the ducts...
