The Advantage of Working with Drosophila Is That Molecular Pathways

The advantage of working with Drosophila is that molecular pathways underlying synaptic plasticity and learning can be identified. When investigators screened for Drosophila with defects in learning and memory they found several, including dunce and rutabaga. What proteins do these genes encode?

A) Adenlyate cyclase and phosphodiesterase
B) cAMP and PKA
C) Serotonin and cAMP
D) Dopamine and the dopamine receptor
E) Dopamine and PKA
