more regulating gene expression

more regulating gene expression. We looked at the mechanisms of gene expression, now we will look at its regulation. Combinations of 3 nucleotides code for each 1 amino acid in a protein. Gene Expression is controlled at all of these steps: DNA packaging Transcription
