Which of the following is TRUE in translation? A. Amino acyl TRNA containing one amino acid is attached to the P site B. Amino acids/peptides attached to the amino acyl tRNA at the P site are transferred to amino acids at the A site, followed by translocation. C. Empty TRNAS are immediately released from the ribosomes D. The E site is always empty after translocation to receive incoming empty TRNAS. E. The anticodon binding to the codon is stringent, i.e. there must be complete complementary base-pairing between the bases in the codon and anticodon before translation can proceed.

Eukaryotic codons are made of DNA, and prokaryotic codons are made of RNA. C. Prokaryotes do not have mRNA, so there are no codons. D. Codons are very similar, no matter whether the cell is prokaryotic or eukaryotic.

The process of translation involves three distinct phases: initiation, elongation, and termination. Which of the following is an accurate statement of a molecular event that occurs during one of the phases? A. All phases of translation require the energy of ATP to fuel molecular processes. B. The first components to assemble in initiation are the large ribosomal subunit, mRNA, and the initiator tRNA molecule. C.

Amino acids are added to the polypeptide chain that sits in the A site of the translation initiation complex.
