The appropriate order for the basic steps of protein synthesis are: a. the elongation reaction transfers the peptide chain from the peptidyl-trna in the p site to the aminoacyl-trna in the a site. b. the p site is occupied by peptidyl-trna carrying the growing polypeptide chain. c. binding of mrna by the small subunit followed by association of a particular initiator aminoacyl-trna that recognizes the first codon. d. the large ribosomal subunit joins the initiation complex, preparing it for the elongation stage. e. the new, longer peptidyl-trna moves from the a site into the p site as the ribosome moves one codon further along the mrna.

The appropriate order for the basic steps of protein synthesis are listed below

Explanation:

First step  D The large ribosomal subunit joins the initiation complex preparing it for elongation stage.

Second step C Binding of mRNA by small Sub unit followed by association of a particular initiator aminoacyl tRNA that recognizes the first codon.

Third step   B The P site is occupied by peptidyl tRNA carrying the growing polypeptide chain.

Fourth step A The elongation reaction transfers the peptide chain from the peptidyl  tRNA in the p site to the aminoacyl tRNA in the A site.

Fifth step   E The new longer Peptidyl tRNA moves from A site into the p site as the ribosome moves one codon further along the mRNA.

organ system-an organ system is a group of organs that work together to perform one or more functions. each does a particular job in the body, and is made up of certain tissues.
