The correct sequence of events in the production of a eukaryotic mRNA is: synthesis in 5' direction 'capping' and polyadenylation of end "splicing': formation of 'signal sequence production of a polycistronic sequence 'splicing' capping with G promoter recognition and initiation termination 'capping' and polyadenylation removal of introns: promoter recognition 'capping' removal of introns polyadenylation initiation process involving a primer messenger to cytoplasm: intron removal termination process transport of polycistronic

Put the following events in the order they occur during translation. One event is NOT part of translation, do NOT include it in your sequence. The finished polypeptide, mRNA, and ribosomal subunits separate. A peptide bond is catalyzed between the first and second amino acids. The ribosome moves so that the third codon is in the A site. A second tRNA with brings in the second amino acid. The small ribosomal subunit associates with the mRNA and moves to the correct start location. The stop codon enters the A site. Translation starts by adding the amino acid that corresponds to the codon at the 5' end of the mRNA. Translation starts when tRNA carrying methionine associates with the first AUG from the 5' end of the mRNA.

Arrange translation steps in the correct order: 1. Ribosome advances until finding start codon. 2. tRNA carrying Met binds to start codon. 3. mRNA binds to the small ribosomal unit. 4. tRNA carrying corresponding amino acids binds to the mRNA, creating peptide bonds between them. 5. Big ribosomal sub-unit closes system. 6. Ribosome moves to the next codon. 7. Stop codon is reached.
