Edition 11ISBN: 9781292139456 Exercise 1
In this chapter, we have focused on large-scale as well as the inter- and intracellular events that take place during embryo-genesis and the formation of adult structures. In particular, we discussed how the adult body plan is laid down by a cascade of gene expression, and the role of cell-cell communication in development. Based on your knowledge of these topics, answer several fundamental questions:
(a) How do we know how many genes control development in an organism like Drosophila ?
(b) What experimental evidence demonstrates that molecular gradients in the egg control development?
(c) How did we discover that selector genes specify which adult structures will be formed by body segments?
(d) How did we learn about the levels of gene regulation involved in vulval development in C. elegans ?
(e) How do we know that eye formation in all animals is controlled by a binary switch gene?
