Steps of protein synthesis:
1 - mRNA attaches to the ribosome
2 - tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA.
3 - tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids.
4 - tRNA carries its specific amino acid to the ribosome.
5 - Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain.
6 -Enzyme "hooks" the amino acid a peptide bond to the last one in the chain forming
