Let $mathcal{C}$ and $mathcal{D}$ be two categories and $F$ and $G: mathcal{C}to mathcal{D}$ be two functors. Suppose $F$ and $G$ have right adjoints $F^{wedge}$ and $G^{wedge}: mathcal{D}to mathcal{C}$.

Now let $T:FRightarrow G$ be a natural transformation.

My question is: does $T$ induce a natural transformation $T^{wedge}:G^{wedge}Rightarrow F^{wedge}$?
