Regulation of gene expression refers to a very broad term that may occur at various levels which results in the formation of desired protein product In eukaryotes the regualtion of gene expression exerted at four levels i Transcriptional level Formation of primary transcript ii Processing level Regulation of splicing iii Transport of mRNA from nucleus to the cytoplasm and iv Translational level Besides these histones plays major role in gene regulation In eukaryotes functionally related genes do not represent an operon but are present on different sites of chromosomes The structural gene called the split gene is a mosaic of exons and introns The development and differentiation of embryo into adult organisms are also a result of the coordinated regulation of expression of several sets opf genes Histones are gene
