Translation is executed in six steps: (i) binding of mRNA to ribosome, (ii) aminoacylation, (iii) initiation, (iv) elongation, (v) termination and (vi) post-translational modification, (i) Binding of mRNA to ribosome I. binding of mRNA to ribosome

identify translation initiation sites genome-wide in budding yeast. They define a class of 149 genes with alternate extended isoforms that initiate at non-AUG start codons. These isoforms are produced in concert with their corresponding canonical isoforms but typically at lower abundance, and are selectively induced during meiosis. Abstract.

The three phases of translation initiation polymerase binds to the DNA strand and moves along until the small ribosomal subunit binds to the DNA. Elongation is initiated when the large subunit attaches and termination end the process of elongation. There are three important steps to the process of translation. There's a beginning step, called initiation, a middle step, called elongation, and a final step, called termination.

Initiation of translation

One of the essential components for the initiation of protein synthesis.IF-3 binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins. Ribosomal subunits are dissociated prior to the initiation reaction. Translation is initiated at the 5′ end of mRNA. Because RNA is synthesized in a 5′‐3′ direction, a bacterial mRNA can start translation while the 3′ sequences are still being transcribed.

Initiation of Translation Protein synthesis begins with the formation of an initiation complex. In E. coli, this complex involves the small 30S ribosome, the mRNA template, initiation factors and a special initiator tRNA. The initiator tRNA interacts with the start codon AUG.

The initiation of translation in prokaryotes reveals that initiation can be subdivided into three distinct steps. In step (1), three initiation factors – called IF1, IF2, and IF3 – bind to the Initiation For translation to begin, the start codon 5’AUG must be recognised. This is a codon specific to the amino acid methionine, which is nearly always the first amino acid in a polypeptide chain. At the 5’ cap of mRNA, the small 40s subunit of the ribosome binds.
