It has been noted in recent years that groups ofgenes are often used at multiple stages and multiple places of development. Comparison of the functions of each group of genes in different developmental context gave rise to the notion of "functional gene cassettes." These groups of genes can often be viewed as sets of tools; each group is suited to carry out a certain operation and may serve similar functions in several developmental processes. For example, neurogenic genes can be thought of as… CONTINUE READING
