A molecule whose concentration determines the developmental fate of a cell is called
A)monomorphic.
B)a juxtacrine protein.
C)a signaling molecule.
D)a morphogen.

Question

Quizplus · Accepted Answer

A morphogen is a molecule whose concentration determines the developmental fate of a cell. This is in contrast to monomorphic molecules, which have a constant or unchanging concentration, juxtacrine proteins, which require direct cell-to-cell contact for signaling, and signaling molecules, which can have a wide variety of roles in cell communication but may not necessarily determine developmental fate.
