Can someone please help me answer the questions above andexplain why did you pick that answer?
Thanks
Which of the following arde A. IF-1 blocks the A-site from binding any other tRNA's the following are not true about the initiatiation of prokaryotic translation. B. IF-2 is responsible for delivering the initiator tRNA to the P site B. IF: 2 is responsible for delivering the initiator tRNA to the P site C. IF-1 blocks the E-site to allow the first peptide bond to form D. The large E. GTP is required to place th subunit of the ribosome is involved only at the end of the initiation process P is required to place the initial tRNA and kick off the initiation factors from the ribosome

Given the wobble rules, what is the fewest number of tRNAs necessary to insert the amino acid Leu into a peptide, and what is the anticodon for each tRNA? There are six codons that specify Leu: UUA, UUG, CUU, CUC, CUA, CUG. Keep in mind all sequences in this question are written 5' to 3'
A) two, with anticodons IAA and GAG
B) two, with anticodons UAA and IAG
C)three, with anticodons IAA, GAG, and UAG
D) three, with anticodons UAA, GAG, and UAG
E)three, with anticodons UAA, IAG, and UAG
A researcher isolates a mutant variant of the bacterial translation factor EF-G. The mutation allows proper folding of the protein and binding of GTP, but does not allow GTP hydrolysis. At what stage would translation be blocked by this mutant protein?
A)Binding of fMet-tRNAfMet to P site.
B) Second aminoacyl-tRNA binding to the ribosomal A site.
C) Formation of peptide bond between amino acids.
D) Movement of ribosome along the mRNA to allow binding of a new EF-TuΓ’ΒΒtRNA in A site.
