Question

You genetically engineer nonadhesive cells to express one variety of cadherins and then mix the cells in various combinations. You then monitor their interactions. What do you observe?
a. The genetically engineered cells adhered preferentially to cells expressing one of the other cadherins.
b. The genetically engineered cells adhered preferentially to cells expressing the same cadherins.
c. The genetically engineered cells did not stick to any other cells.
d. The genetically engineered cells died.
e. The genetically engineered cells migrated to a different location.

Answer 1

Answer:

The correct answer is b. The genetically engineered cells adhered preferentially to cells expressing the same cadherins.

Explanation:

As the cells were nonadhesive, when engineered they express affinity for cells expressing the same cadherins. Although depending on the engineering the cells could express different affinity.
