| | | The relationship between the information contained in DNA and the structure of proteins was determined: there is a genetic code, which creates a correspondence between the succession of nucleotides in the DNA sequence and a series of amino acids in proteins. Monod and Jacob also demonstrated how certain specific proteins, called regulative proteins, latch onto DNA at the edges of the genes and control the transcription of these genes into messenger RNA; they direct the "expression" of the genes. | | | The relationship between the information contained in DNA and the structure of proteins was determined: there is a genetic code, which creates a correspondence between the succession of nucleotides in the DNA sequence and a series of amino acids in proteins.
