Question
Chapter 14.1, Problem 1CC
Summary Introduction
To determine: The way by which gene regulation underlie different morphologies of various types of cells.
Introduction: Process of gene regulation can be defined as a way by which expression of genes takes place to form functional products. These functional products can be proteins and RNA (Ribose

How does gene expression influence the behavior of cells that contain the same genome (genetic information)? In other words, why do cells that belong to the same multicellular organism have a different structure and function?
How do cells control gene expression? How do cell "switch" genes on/off? Draw a flow chart to match?
If each cell in your body contains the same DNA sequence, how would the regulation of Gene X differ quantitatively in the intestinal epithelial cells from that of a neuron? How would the regulation of Gene X differ qualitatively, resulting in different products in the two cell types?
