Which of the following describes a key difference among the 20 amino acids that are used to make proteins?
Understand the Problem
The question is asking about the key differences among the 20 amino acids used to make proteins, focusing on specific structural or chemical characteristics that distinguish them.
Answer
The chemical properties of the R groups can make some amino acids hydrophobic.
The final answer is C. The chemical properties of the R groups can make some amino acids hydrophobic.
Answer for screen readers
The final answer is C. The chemical properties of the R groups can make some amino acids hydrophobic.
More Information
The distinct R groups on the 20 amino acids give them unique properties, such as hydrophobicity or hydrophilicity, key in the folding and function of proteins.
Tips
A common mistake is to confuse the R group with the amino or carboxyl groups, which are consistent in all amino acids.
