WebbProtein synthesis Proteins are made by ribosomes with the sequence of amino acids controlled by the sequence of bases contained within DNA DNA cannot travel out of the nucleus to the ribosomes (it is far too big to pass through a nuclear pore) so the base code of each gene is transcribed onto an RNA molecule called messenger RNA (mRNA).

The phosphate and sugar section of the nucleotides form the ‘backbone’ of the DNA strand (like the sides of a ladder) and the base pairs of each strand connect to form the rungs of the ladder. It is this sequence of bases that holds the code for the formation of proteins. The DNA helix is made from two strands of DNA held ...
