D) gradient regulated
E) attenuation

Question

Quizplus · Accepted Answer

Determination refers to the regulatory events that establish a specific pattern of gene activity and developmental fate for a given cell. It is the process by which a cell commits to a particular developmental pathway and becomes irreversibly specialized in its function. Differentiation refers to the process by which cells acquire specialized structures and functions, which is largely driven by the changes in gene activity established during determination. Lysogeny refers to the state of a bacteriophage in which it integrates its genome into the host bacterium's chromosome and replicates with it, whereas attenuation refers to the reduction in the virulence or infectivity of a microbe due to various factors. Gradient regulation refers to the process by which morphogens, signaling molecules that create concentration gradients, direct cells to form different cell types in a developing embryo.
