Following statements are regarding to the wingless gene in drosophila.
A.
In the cells transcribing the wingless gene, wingless mRNA is translocated by
its 3’UTR to the apex of the cell. At the apex, the wingless message is translated
and secreted from the cell.
B.
The cells expressing engrailed can bind this protein because they contain
Patched, which is the Drosophila membrane receptor protein for Wingless.
C.
Binding of Wingless to Frizzled activates the hedgehog signal transduction
pathway, resulting in the continued expression of engrailed.
D.
Wingless protein also acts in an autocrine fashion, maintaining its own
expression.
