Multiple Choice
Overexpressing a single isoform of Dscam in a small subset of projection neurons shifted their dendrites to a neighboring glomerulus. Unexpectedly, the axons of their partner (wild-type) ORNs also shifted to the new glomerulus. Thus, Dscam appears to play a similar role to that of:
A) Sema1A.
B) Sema2B.
C) Ten-a or Ten-m.
D) Caps.
E) None of the above
