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.

Many antibiotics are effective as drugs to fight off bacterial infections because they inhibit protein synthesis in bacterial cells. Using the information provided in the following table that highlights several antibiotics and their mode of action, discuss which phase of translation is inhibited: initiation, elongation, or termination. What other components of the translational machinery could be targeted to inhibit bacterial protein synthesis? Antibiotic Action 1. Streptomycin Binds to 30S ribosomal subunit 2. Chloramphenicol Inhibits peptidyl transferase of 70S ribosome 3. Tetracycline Inhibits binding of charged tRNA to the A site of the ribosome 4. Erythromycin Binds to free 50S particle and prevents formation of 70S ribosome 5. Kasugamycin Inhibits binding of tRNAfMet 6. Thiostrepton Prevents translocation by inhibiting EF-G

Select all of the factors in the list below that play a role in the translation initiation of eukaryotic cells. the Kozak sequence eIF4G 3'-polyA tail fMet-tRNA the Shine-Dalgarno sequence eIF4E 5'-CAP PolyA Binding Protein (PABP)
Find the events from prokaryotic translation from the list below and list them below in order, by letter, from earliest to latest during translation A. Incoming tRNA occupies the A-site B. Small ribosome binds to Shine Dalgarno sequence C. 5’ methyl cap binds small ribosome D. Large ribosome subunit binds the small ribosome subunit E. P-site tRNA peptide is attached to the amino acid of the A-site tRNA. F. f-Met tRNA binds to P site G. Small ribosomal subunit binds mRNA H. Peptide released from complex.
Use the numbers below to indicate the correct order of events (from left to right) during the process of translation initiation in bacteria. large ribosomal subunit binds to the complex. IF3 is released. The small ribosomal subunit associated with IF1, IF2, and IF3 binds to the Shine-Dalgarno sequence on the mRNA. tRNA charged with f-methionine binds to the AUG codon at the P site. IF1 and IF2 are released, leaving the A site available for the second charged-tRNA to bind the codon at the A site. 3 1 5 4 2 2 1 4 5 3 1 3 5 2 4 3 4 2 1 5 4 2 1 3 5
Indicate which of the following items are associated with transcription or translation. This could be in prokaryotes or eukaryotes, or both. Group of answer choices: Translation OR Transcription Sigma binds to the promoter mRNA binds to the small ribosomal subunit Spliceosomes remove introns and splice together exons Nucleotides are added from the 5' to 3' end tRNA anticodon binds to the corresponding mRNA codon STOP codon results in termination
Explain the steps of Eukaryotic Translation Initiation. 1. Formation of preinitiation complex. 2. Initiatior tRNA attachment. 3. Formation of initiation complex and scanning. 4. RIbosome assembly and translation initiation.
Which of the following statements about translation is false? In eukaryotes, the 5' cap and the 3' poly(A) tail are involved in translation initiation. Peptidyl-transferase activity during translation is the property of a ribozyme. A base at the first position of an anticodon on the tRNA would pair with a base at the third position of the mRNA. The growing peptide chain is transferred from the tRNA in the P site to the tRNA in the A site. Ribosomes move along an mRNA in the 3’ → 5' direction.
