A classmate has asked for help identiing a particular disease caused by an inherent mutation This disease causes a person to lose lungS unction, and it makes them prone to lung infections The disease also affects the digestive system especialy the pancreas What disease is this
person suffering trom?
Down syndirome

uscular dystrophy
gstic fbrosis
Duchenne muscular dystrophy
cancer

Down Syndrome wouldn't cause this.

Cancer is where your blood cells are involved so no.

Duchenne muscular dystrophy is where your limbs are effected so no.

Cystic fibrosis affects the cells that produce mucus, sweat, and digestive juices. It causes these fluids to become thick and sticky. They then plug up tubes, ducts, and passageways.

Symptoms vary and can include cough, repeated lung infections, inability to gain weight, and fatty stools.

So yes Cystic fibrosis is possibly the answer

BUT

Muscular dystrophy can also cause this as your muscles weaken over time. But most likely its Cystic fibrosis

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."
