The primary structure is a straight chain of polypeptides.

For initiation of the translation process, the ribosome binds to the mRNA at the start codon recognized by the initiator tRNA. The ribosome then proceeds to the elongation phase of protein synthesis. During this stage, the complexes formed by amino acids are linked to tRNA, sub sequentially to bind to the appropriate codon in mRNA by forming complimentary base pairs with the tRNA anticodon. The ribosome moves from codon to codon along the mRNA. Amino acids are added one by one, translated into polypeptide sequences dictated by the DNA and represented by mRNA. At the end, release factor binds to the stop codon, thus terminating the translation stage and completing the protein synthesis process. The complete polypeptide is released from the .

So basically, different Amino acids are added one by one per codon, translated into polypeptidic sequences dictated by DNA and represented by mRNA.

Proteins consist of amino acids joined together via peptide bonds to form polypeptides.

פטנט US6783957 - Method for synthesis of polypeptides …

Because of the increased demands of peptide-based biomaterials for drug delivery and tissue engineering, efficient protein purification techniques must be used.

Chapter 5 : Amino Acids and Peptides

Although ultimately both polypeptides and proteins are chains of amino acids, in order to form a protein the amino acids have to be in a specific order, contrasting to polypeptides which can have amino acids in any order.

In some cases, smaller polypeptides coded for by two or more genes must be joined together to produce a functional protein.

9 Steps of Protein Synthesis Flashcards | Quizlet

Since the vast majority of genes are transcribed into mRNA and mRNA is subsequently translated into polypeptides or proteins, most genes code for protein synthesis.

Two of the polypeptides have molecular weights of 45,000 and athird has a molecular weight of 44,000.

Purification of polypeptides and proteins derived from ..

Elastin-like polypeptides can undergo protein purification so that a single type of protein can be isolated from a complex mixture.

Polypeptides for Immune Surveillance and ..

The amino acids are joined to form proteins by peptide bonds. The formation of peptide bonds requires a good amount of energy. Therefore, in the first phase of translation for protein synthesis, the amino acids are activated in the presence of ATP and linked to their cognate tRNA (transfer RNA). This process is called as charging of the tRNA or aminoacylation of tRNA. If two such charged tRNA are brought close enough, the formation of peptide bond between them is favored energetically. This function occurs inside the , as it contains two sites for subsequent amino acids to bind to and thus be close enough for bonding.
