Problem: What is the proper sequence of events in the formation of a peptide bond?A. A-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the P-site tRNA peptide to the amino acid of the A-site tRNA.B. P-site tRNA bears the incoming amino acid. The A-site tRNA carries the growing peptide chain. Peptide bond formation attaches the A-site tRNA peptide to the amino acid of the P-site tRNA.C. E-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the E-site tRNA amino acid to the peptide of the P-site tRNA.D. A-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the A-site tRNA amino acid to the peptide of the P-site tRNAE. P-site tRNA bears the incoming amino acid. The A-site tRNA carries the growing peptide chain.

What is the proper sequence of events in the formation of a peptide bond?

A. A-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the P-site tRNA peptide to the amino acid of the A-site tRNA.

B. P-site tRNA bears the incoming amino acid. The A-site tRNA carries the growing peptide chain. Peptide bond formation attaches the A-site tRNA peptide to the amino acid of the P-site tRNA.

C. E-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the E-site tRNA amino acid to the peptide of the P-site tRNA.

D. A-site tRNA bears the incoming amino acid. The P-site tRNA carries the growing peptide chain. Peptide bond formation attaches the A-site tRNA amino acid to the peptide of the P-site tRNA

E. P-site tRNA bears the incoming amino acid. The A-site tRNA carries the growing peptide chain. Peptide bond formation attaches the P-site tRNA amino acid to the peptide of the A-site tRNA.
