a) The elongation level of translation in eukaryotes requires three elongation factors, eEF-IB, eEF-1A and eEF-2, that have similar functions to their prokaryotic counterparts EF-G and EF-Tu, EF-Ts.

b) Although most codons encode the same amino acids in together eukaryotes and prokaryotes, the mRNAs synthesized within the organelles of similar eukaryotes use a dissimilar of the genetic code.

c) In During elongation in bacteria, the deacylated tRNA in the P site shifts to the E site prior to leaving the ribosome. In contrast, whereas the condition  is  still  not  completely  clear,  in  eukaryotes  the  deacylated  transfer RNA appears to be ejected straightly from the ribosome.
