What do chains of amino acids build?

Proteins

Explanation:

Chains of amino acids linked together by peptide bonds form proteins. The properties of the amino acids in the chain dictates the complex structure and function of proteins, including folding, enzymatic activity, and binding sites.

The order of amino acids in the chain is dictated by DNA via the transcription of an intermediate molecule of mRNA, which is then translated into a sequence of amino acids.

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.
