Summary Introduction

To describe: The ways by which the polycomb genes control the expression of two very different sets of homeotic genes.

Introduction: Different sets of the regulatory genes are used in Drosophila and Arabidopsis to establish the axis of the body in these organisms. In Drosophila, hox genes are the homeotic genes that belong to the homeobox gene family. In Arabidopsis, MADS-box protein is the family of transcription factors to which floral homeotic genes belong.

The metabolic pathway below is used for the production of the purine nucleotides adenosine monophosphate (AMP) and guanosine monophosphate (GMP) in eukaryotic cells. Assume each arrow represents a reaction catalyzed by a different enzyme. Using the principles of feedback inhibition, propose a regulatory scheme for this pathway that ensures an adequate supply of both AMP and GMP, and prevents the buildup of Intermediates A through G when supplies of both AMP and GMP are adequate.
