Answer:
Option-1 and 3
Explanation:
Cadherin is the protein complex present in the cell which is responsible for the sticking together of cell in tissue-like in the skin. The cadherin junctions allow the communication between the cells and the loss of the cadherin could cause cancer.
The cadherin junction is involved in the signalling pathway in the cells like in the Rho GTPase signalling, Ras signalling and many others which shows that they are responsible for the biological processes in an organism.
Thus, Option-1 and 3 are correct.
