D)They increase greatly in size.
E)Their nuclei disintegrate.

Question

Quizplus · Accepted Answer

Laminin is an extracellular matrix protein that plays a critical role in cell adhesion and migration. Primordial germ cells rely on laminin to properly migrate to the developing gonad. Exposure to laminin-specific antibodies would disrupt the ability of these cells to effectively migrate, potentially resulting in developmental abnormalities or even loss of these cells. Therefore, choice B, that their movement to the developing gonad is disrupted, is the best answer.
