put the following processes of protein synthesis translation steps in the correct order :
A- the next aa2-tRNA attach to the second codon on mRNA located in A site
B- then large ribosomal subunit binds the small ribosomal subunit forming an active ribosome
C- the ribosome breaks down and the mRNA dissociates and protein is released
D- the ribosome small subunit binding to the mRNA
F- the first amino acid moves to exit site and leaves the ribosome
G- ribosome moves on mRNA and by 1 codon this process is called translocation
H- the tRNA is charging with amino acid at 3' OH end
i - the aa1-tRNA carries the anticodon attaches directly with mRNA in the start codon located in P site

The first step in the above order i.e, (H) represents the activation of amino acides and their attachment to tRNAs.
The next three steps i.e, (D),(B),(I) are included in the initiation phase of the protein translation process.
The three next steps further i.e, (A),(G), and (F) are included in the elongation phase of the translation process.
The last step i.e, (C) is included in the termination phase of the translation process.
Thanks.
