Which step in translation initiation is unique to eukaryotes? which step in translation initiation is unique to eukaryotes? binding of ribosomes to the 5' cap of the mrna formation of the preinitiation complex ribosome assembly formation of the initiation complex translocation of the ribosome in the 3 direction?

The step in translation initiation that is unique to the eukaryotes is:

formation of the preinitiation complex ribosome assembly

Here are the processes involved in the Translation Initiation of Eukaryotes

1) 5'cap is used to position the mRNA on the 40S ribosomal subunit
2) ribosome scans down the mRNA looking for an AUG.
3) There is an initiator methionine-tRNA
4) The initiating AUG codon is often within a consensus sequence called the Kozak sequence (5'-ACCAUGG-3')
5) After binding the cap, ribosomes scan down the mRNA until the Kozak sequence is reached and translation begins
6)The poly (A) tail and 5'-cap binding proteins help the initiation complex form

The answer is cjust typing because the minimum is 20 bl bl bl
