Question

Quizplus · Accepted Answer

The signals that inform a cell about its position relative to other cells in the embryo are called morphogens. Morphogens are chemical signals that are secreted by cells and diffuse through the surrounding tissue to create a concentration gradient. These concentration gradients provide cells with positional information, and cells respond by activating different sets of genes that control cell fate and differentiation. Master control genes are the genes that respond to these morphogen gradients and thus are essential components of the signaling pathways that inform cells about their position in the developing embryo. Therefore, the only choice that matches this description is C, where "master control genes" are responsive to "chemical" signals.
