ABSTRACT
Every cell in an organism contains the same genetic code, with the functional role of cell being controlled by differential gene expression. Protein coding regions in a eukaryotic DNA only account for 2% of the genome. However, noncoding nuclear DNA has been shown to be important for regulation of gene expression with the mechanisms of gene regulation being coordinated by the presence of biologically significant DNA sequence patterns observed within the noncoding in the neighboarhood of genes (Kliensmith and Kish 1995).
