In one trial, you determine a sequence with glycine as the N-terminal amino acid and asparagine as the C-terminal amino acid. In another trial, your results indicate phenylalanine as the N-terminal amino acid and alanine as the C-terminal amino acid. How do you reconcile this apparent contradiction?arrow_forward
- REFLECT AND APPLY You are in the process of determining the amino acid sequence of a peptide.

What might have been the problem that caused it?arrow_forwardREFLECT AND APPLY Would you expect mRNA or rRNA to be degraded more quickly in the cell? Why?arrow_forwardREFLECT AND APPLY The enzyme D-amino acid oxidase has a very high turnover number because the D-amino acids are potentially toxic. The KM for the enzyme is in the range of 1 to 2 mM for the aromatic amino acids and in the range of 15 to 20 mM for such amino acids as serine, alanine, and the acidic amino acids. Which of these amino acids are the preferred substrates for the enzyme?arrow_forward
