Which of the following statements correctly summarizes the steps of protein synthesis? Transcription & Translation a.) mRNA copies DNA into an amino acid chain in the nucleus. Once out of the nucleus, it folds into a protein by ribosomes.

b.) DNA is transcribed into mRNA in the nucleus. mRNA then leaves where it is read by a ribosome to form an amino acid chain.

c.) DNA is transcribed into amino acids in the nucleus before it leaves into the cytoplasm. In the cytoplasm it binds with mRNA to form amino acids.

A. Is the correct answer to your question.

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.
