Initiation:when a thing(a small subunit of a ribosome charged with a tRNA+the amino acid methionine) met mRNA, it will begin to check it. Then when it finds the start AUG sequence, the codon (triplet) amino acid methionine, the large subunit was added 1 small, to form a complete and ribosomal protein synthesis is initiated.
Elongation:The new tRNA + amino acids into the ribosome, the next codon downstream of the AUG codon. If it is the anti-codon of the mRNA codons matching base pairs and its ribosome linkable two amino acids together. The ribosome then move forward a triple and a new tRNA + amino acids can enter ribosome and the process repeated.
Termination:When the ribosome reaches the stop codon of three promoters, such as UGA, there is no corresponding tRNA to the sequence. Instead of terminating in ribosomal protein binding, stimulation of protein, and the mRNA ribosome dissociation. When the ribosome is composed of mRNA, its large and small subunit dissociation released. Small subunit can now load a new tRNA + methionine, and start the translation again. Some cells require large amounts of specific proteins. Protein is usually converted some further changes, it becomes fully functional.
