a critical role in transcriptional regulation. Chromatin can inhibit access of transcription factors to the DNA and can thereby repress gene expression. In eukaryotic organisms, with their very large number of genes (approximately 40 310 in mammals), this means that the ground state of gene expression is for genes to be turned off. Activation

For the purpose of our discussion of the Central Dogma of Molecular Biology, we can consider a gene to comprise one or more segments of one or more molecules that need to be copied to carry out a particular function. Continuing with this simple definition of a gene, we can say that gene expression comprises processes involving

hydrogenase encoding hupLgene occurs during cellular differentiation to heterocysts which are specialized in N 2fixation. Developmentally controlled gene rearrangments, resulting in the excision of a 10.5kb DNA element from the hupLgene, encoding the large subunit of an NiFe uptake hydrogenase, lead to activation of hydrogenase gene expression.
