What is the elongation process of translation?

Elongation (“middle”): in this stage, amino acids are brought to the ribosome by tRNAs and linked together to form a chain. Termination (“end”): in the last stage, the finished polypeptide is released to go and do its job in the cell.

What are the steps of elongation?

During the elongation stage, the ribosome continues to translate each codon in turn. Each corresponding amino acid is added to the growing chain and linked via a bond called a peptide bond. Elongation continues until all of the codons are read.

What are the 4 steps of translation?

Translation happens in four stages: activation (make ready), initiation (start), elongation (make longer) and termination (stop). These terms describe the growth of the amino acid chain (polypeptide). Amino acids are brought to ribosomes and assembled into proteins.

What is the process of translation step by step?

Steps of Translation There are three major steps to translation: Initiation, Elongation, and Termination. The ribosome is made of two separate subunits: the small subunit and the large subunit. During initiation the small subunit attaches to the 5′ end of mRNA. It then moves in the 5′ → 3′ direction.

What are the 6 steps of translation?

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.

What is the initiation step in translation?

The first step in translation, initiation, begins when an mRNA binds to a free light ribosomal subunit. A transfer RNA molecule then brings the first amino acid to the light subunit of the ribosome. Other protein factors join this assemblage and then the heavy ribosomal subunit binds to complete initiation.

What is the end result of translation?

the end result of translation is the formation of a new polypeptide chain.

What is the function of the elongation?

Elongation factors are a set of proteins that function at the ribosome, during protein synthesis, to facilitate translational elongation from the formation of the first to the last peptide bond of a growing polypeptide. Bacteria and eukaryotes use elongation factors that are largely homologous to each other, but with distinct structures and different research nomenclatures.
