Translation is the second stage of protien synthesis, when the amino acids are assembled into a polypeptide. They are assemebled into a sequence dictated by a sequence of codons on the mRNA. The genetic code is now translated into a sequence of amino acids.

RIbosomes 

RIbosomes are assembled in the nucleolous of eukaryotic cells, from ribosomal RNA and protein. Each is made up of two subunits and there is a groove, which the length of mRNA can fit into. The ribosome then moves across the mRNA reading the code and assembling the amino acids in the correct order to make it a functioning protein. 

The sequence of amino acids is critcal for a number of reasons: 

  • Forms a primary structure 
  • The primary structure determines the tertiary structure.
