Each type of cell has specific roles. Every cell has a master plan for its roles and the tools to implement that plan. The 20,000 to 30,000 genes in the genetic code of the DNA provide the plan. The RNA implements the plan utilizing nutrients stored in the inventory of the cells. Proper functioning of each cell depends on having an adequate supply of the nutrients it needs.
