The most commonly occurring mutation in people with cystic fibrosis is a deletion of a single codon. this mostly likely results in

It would result in a polypeptide which has a missing amino acid.  The genetic mutation that occurs in a person with cystic fibrosis is called frameshift mutation which is caused by an insertion or deletion of nucleotides that is not divisible by three in a sequence of DNA.

answer; the above answer to the above statement is (true)

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
