Question

All amino acids have a central carbon with four components attached to it. One of these components is called the R group. Which of the following best describes the R group?
A.The R group gives amino acid unique characteristics.
B.The R group helps amino acids replicate.
C.The R group is what stabilizes the amino acid.
D.The R group is the same in all amino acids.

Answer 1

I believe the answer is A. The R group gives amino acid unique characteristics. Hope this helps :)

Answer 2

The statement that best describes the R group of an amino acid is: R group gives amino acid unique characteristics.

AMINO ACID:

• Amino acids are monomers of a molecule called proteins. Amino acids are structurally made up of three components.

• The three components that make up the structure of an amino acid are: amino group (-NH2), carboxyl group (-COO), and a R side chain.

• The amino and carboxyl groups are the same in all amino acids, however, no two amino acids have the same R side chain.

• This means that the R group distinguishes one amino acid from the other.

• Therefore, statement that best describes the R group of an amino acid is: R group gives amino acid unique characteristics.
