Cells Expressing Either N-Cadherin (A), High Levels of E-Cadherin (B)

question 9

Short Answer

Cells expressing either N-cadherin (A), high levels of E-cadherin (B), or low levels of E-cadherin (C) have sorted themselves out on a substratum in a cadherin-dependent manner as shown in the schematic drawing below. Which cells (A to C) would you expect to correspond to white, gray, and black in the drawing, respectively? Your answer would be a three-letter string composed of letters A to C only, e.g. CAB.
