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-TuâtRNA in A site.
