Fakunding and Hershey mixed [32P]IF2 (blue) and
[3H]fMet-tRNAfMet (red) with 30S ribosomal subunits to
form 30S initiation complexes. Then they added 50S ribosomal
subunits in the presence of either (a) GDPCP, or (b) GTP, and then
analyzed the complexes by sucrose gradient ultracentrifugation. How
to interpret the results that there is difference for the binding
of IF2 to the ribosome between the addition of GTP and GDPCP in the
experiments?

In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...

Which is incorrect about the initiation of translation? Select one: a. 30S subunit binds to mRNA first by recognizing the Shine-Dalgarno sequence on mRNA. b. In bacteria, most of the starting Met codon is specifically for N-formyl methionine (fMet). c. After fMet-loaded tRNA is bound, the 50S subunit binds to make the complete translational complex. d. A complete ribosome complex migrates on an mRNA until it finds the Shine-Dalgarno sequence. e. All of these

QUESTION 35 Tetracycline is an antibiotic used to treat bacterial infections in humans because it prevents the growth and spread of bacteria. This drug is known to bind strongly and specifically to the A site in the 30S ribosomal subunit. Based on this information you would expect that: a. tetracycline does not affect translation in eukaryotic cells. b. tetracycline inhibits RNA splicing in prokarytes. c. tetracycline will prevent the small ribosomal subunit from binding to the Shine-Dalgarno sequence. d. tetracycline...

Which of the following statements best describes the initiation of translation? A tRNA with the anticodon, AUG, enters the ribosomal complex and binds to the mRNA at the A site. b) The large and small ribosomal subunits scan the mRNA in the 3'-5 direction until the promoter is reached. 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...
