Question
Chapter 19, Problem 3DQ
Summary Introduction
To review:
The factors which are considered as ”reactive” activators and inhibitors in the active zone, during the pattern formation in organogenesis.
Introduction:
Turing's model is described as one of the very important models in developmental biology, which is formulated by the Alan Turing (1952), one among the founders of computer science. The reaction-diffusion mechanism is a mathematical model which predicts alternating areas of high and low concentrations of some substance. He also explains the generation of complex patterns from the substances which are initially distributed homogeneously. The reaction part of this model is unique for this mechanism. This model explains that molecular prepatterns are dependent on reactant's interactions which spontaneously generate a non uniform pattern.

This is one given problem on my homework assignment for developmental biology. Thank you for the help!Describe the effects of FGF and RA on each other in limb bud development. Give a specific example of their effects on each other in this capacity. Knowing this, propose a question/hypothesis to investigate the mechanism of how a specific morphogen controls pattern if you know that the morphogen is both necessary and sufficient AND is expressed in the correct spatial/temporal frame.
