During Codon recognition (a) the ribosome moves towards the 3’ end of the mRNA (b) a tautomeric shift occurs (c) a peptide bond forms (d) anticodon and codon pairing occurs (e) all of the above
Which of the following statements best describes the initiation of translation? A) The large and small ribosomal subunits scan the mRNA in the 3'–5' direction until the promoter is reached. B) A tRNA with the anticodon, AUG, enters the ribosomal complex and binds to the mRNA at the A site. C) The mRNA containing the start codon, AUG, sits at the P site and forms a complex with the corresponding tRNA, and the large and small ribosomal subunits. D) The mRNA attaches to the large ribosomal subunit and once the start codon reaches the A site, the tRNA binds and the small subunit completes the complex.

What happens when a stop codon is reached by a ribosome? A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome dissociates. A separate peptidyl transferase then releases the protein from tRNAter. A termination tRNAter binds to the codon and the growing peptide is transferred to it. When the peptidyl-tRNAter reaches the P site, the ribosome is signaled to release the protein. The ribosome then is likely to dissociate. A release factor binds to the codon and is used to release the growing peptide from the P site tRNA. A termination tRNAter binds to the codon and is used to release the growing peptide from the P site tRNA. The ribosome then is likely to dissociate.
Which of the following are stages of translation? Select all that apply. A. A tRNA binds to the second codon and its carried amino acid forms a peptide bond with methionine. B. As the ribosome moves from codon to codon, amino acids brought by successive tRNAs to the ribosome form a growing polypeptide. C. When the ribosome reaches a stop codon, its subunits detach, and the mRNA and new polypeptide are released. D. Ribosomal subunits and a tRNA carrying methionine converge on the start codon of an mRNA. E. The binding of a tRNA to the third codon causes the ribosome to release the first tRNA and move to the next codon.
The codon and anticodon are base-paired together during the process of translation. Which of the following is correct regarding the relationship between anticodon and codon? A. The tRNA anticodon UCU pairs with the AGA mRNA codon. B. The tRNA anticodon is read from the 5’ to the 3’ end. C. A tRNA anticodon can pair with only one mRNA codon. D. The mRNA codon ACG base pairs with the tRNA anticodon TGC.
