What is the question being addressed by the modellers in Coopey 2007 & what is their hypothesis?

Consider Coopey et al’s 2007[1] & 2008[2] papers. Write a series of paragraphs addressing the
following points:
1) What is the question being addressed by the modellers in Coopey 2007 & what is their hypothesis?
2) How do the equations in the paper enable the group to address their question? Give a general
description of the model. Then describe the meaning of each term in equations (1) and (2).
3) Why are there two phases in the model? Describe the biological motivation for the phases and
explain how they are realised in the model.
4) Why were partial differential equations chosen instead of Boolean networks?
5) What prediction did the model make about the biological system and how could this be tested
experimentally?
6) Describe the work in Coopey 2008 and discuss the implications of this study on work in Coopey
2007.
