Question

BlackTom AI · Accepted Answer

Consider the question asking for a feature of cadherins.
Option a: 'They bind cadmium ions.' This is incorrect; cadherins are not defined by binding cadmium; their key property is calcium-dependent adhesion, not metal binding.
Option b: 'They are cell-surface associated.' This is correct. Cadherins are transmembrane proteins located on the cell surface and mediate homophilic cell–cell adhesion in a calcium-dependent manner.
Option c: 'They are secreted by one cell and bind to a neighbouring cell.' This is inaccurate for cadherins, which are membrane-spanning, not secreted proteins that float freely to bind neighbors.
Option d: 'They are morphogens.' This is incorrect; morphogens are signaling molecules that pattern tissue development, whereas cadherins function as adhesion molecules on the cell surface, not as diffusible morphogens.
