Answer:
The answer is : a) Cadherin proteins in metastasizing cancer cells are likely to have mutations that make them less "Sticky".
Step-by-step explanation:
Cell-cell adhesion is mediated by cadherins that regulate contact formation and stability between cells and thus are important for tissue morphogenesis and homeostasis. Cadherin (more specifically, E-Cadherin) loss of function is thought to enable metastasis due to the impaired intercellular contacts that could lead to increased motility and eventually to invasion and colonization of surrounding tissues.
