PPT-Ribosomes are here the protein synthesized in the cells

From RNA to Protein Translation Steps of Translation MESSENGER RNA Polypeptide chains are specified by open reading frames Three possible reading frames of E coli trp leader sequence An mRNA sequence is decoded in set of three nucleotides. Essential idea: Proteins have a very wide range of functions in living organisms.. One of the central ideas in Biology is that structure dictates function. Above you can see insulin in its secondary, tertiary and quaternary structures. Polypeptides vary hugely in the combination and number of amino acids that they are composed from. Even if we consider a single polypeptide it's properties, and hence it's function, would vary greatly depending on it's level of structure. Insulin can exist in all these forms, but the active form, which controls blood glucose levels, is a the tertiary structure.. but also found free in the cytoplasm . Site of protein synthesis.
