How the cells are able to synthesize different molecules, in terms of cytoplasmic determinants and gene regulation. Concept introduction : During embryonic development, the zygote is differentiated to form mature cells with a specific structure and function. The process is known as cell differentiation . As the embryo enlarges and the cell number increases, the cells communicate with each other in the embryo. Certain cytoplasmic determinants and signals from other nearby embryonic cells regulate the specific gene expression. Signal molecules regulate gene expression by the activation and deactivation of specific genes of other cells in a process known as induction . These processes together determine the fate of embryonic cells.

a) Create a diagram which illustrates the typical signalling mechanism of action of kinase- linked receptors and possible routes of communication (autocrine etc.). Should show the specific molecules involved, the mechanisms of signal transduction and indicate the different pathways that are activated. It should include a specific example of a receptor, ligand and signalling pathway for each general class. Include as wide a variety of ligands and modes of action as you can. for a novel pathway.

Non-canonical Hedgehog signaling results in actin cytoskeleton rearrangements, leading to cellmovement and changes in cell shape. Describe how changes to the actin cytoskeleton lead to cellmovement and changes in cell shape.You do not need to draw out the signaling pathway again (#1b). Your answer should focus onthe changes to the actin cytoskeleton. Drawings will be helpful!

Compare and contrast GPCR and RTK signaling. What role does GTP play in each? What role does phosphorylation play? How do these two signaling types compare to steroid signaling with respect to gene activation?
