Question

ich of the following statements about similarities and differences in prokaryotic and eukaryotio n are TRUE? (Select all that apply.) nitiation in prokaryotes and eukaryotes begins with a formylmethionine rokaryotic and eukaryotic ribosomes are different sizes Prokaryotic ribosomes are sensitive to antibiotics that do not affect eukaryotic ribosomes G) D) Prokaryotic mRNAs are short-lived. Eukaryotic mRNAs vary in their halt-life Recognition of the start codon in prokaryotes and eukaryo tes involves the 5' cap, the 3 poly(A) don and the Kozak sequence near the start co F) Prokaryotic initiation, elongation, and termination G) Transcription and translation routinely occur H) Elongation involves the formation of a the tRNAs in the P and A sites of the ribosome in both prokaryotes and eukaryotes from those in eukaryotes factors are
