Protein Synthesis AP Biology

Which of the following requires the dehydration reaction of two amino acids?

• Carboxyl group of first amino acid binds with carboxyl group of second amino acid

• Carboxyl group of first amino acid binds with amino group of second amino acid

• R group of first amino acid binds with R group of second amino acid

• Amino group of first amino acid binds with amino group of second amino acid

Phosphorous (P) is an important nutrient for plant growth. Figure 1 shows Arabidopsis thaliana plants grown under phosphorus‐sufficient (left) and phosphorus‐starved (right) conditions for six weeks. Which of the following is the most likely reason for the difference in leaf growth?

• The phosphorus-starved plant was unable to synthesize both the required proteins and lipids, limiting growth.

• The phosphorus-starved plant was unable to synthesize both the required proteins and carbohydrates, limiting growth.

• The phosphorus-starved plant was unable to synthesize both the required nucleic acids and lipids, limiting growth.

• The phosphorus-starved plant was unable to synthesize both the required carbohydrates and nucleic acids, limiting growth.

If there is an error in transcription, what could happen as a result?
