Describes the steps of translation initiation (how does the ribosome find the mRNA and what is the first step of initiation, include the role of IF3, what occupies the E, P and A sites) in prokaryotes. Name two ways that eukaryotic initiation is different . Now describe elongation in prokaryotes - what occupies each of the A, P and E sites during elongation. What are the roles of Ef-Tu and Ef-G ? Where is energy spent in the process ? You may either draw pictures of describe the processes in words â you do not need to describe termination.
