    In animals, four separate families of cell-cell adhesion proteins are listed in Column A and their functional characteristics are given in Column B.
    Column A Column B
    A. Integrin 1. Lectins that mediate a variety of transient, cell-cell adhesion interactions in the bloodstream
    B. Cadherin 2. Contains extracellular Ig-like domains and are mainly involved in the fine tuning of cell-cell adhesive interaction during development and regeneration
    C. Ig super family 3. Mediates \[C{{a}^{2+}}\]dependent strong family hemophilic cell-cell adhesion
    D. Selecting 4. Trans membrane cell adhesion protein that acts as extracellular matrix receptors.
    Which one of the following is the correct combination?

    A) 1\[\to \]A, 2\[\to \]B, 3\[\to \]C, 4\[\to \]D

    B) 2\[\to \]A, 3\[\to \]B, 4\[\to \]C, 1\[\to \]D

    C) 3\[\to \]A, 4\[\to \]B, 1\[\to \]C, 2\[\to \]D

    D) 4\[\to \]A, 3\[\to \]B, 2\[\to \]C, 1\[\to \]D

    Correct Answer: D

    Solution :

    Integrin Trans membrane cell adhesion proteins that act as extracellular matrix receptors. Cadherin Mediates \[C{{a}^{2+}}\] dependent strong hemophilic cell-cell adhesion. Ig super family Contains extracellular Ig like domains and are mainly involved in the fine tuning of cell-cell adhesive interaction during development and regeneration. Selecting Lectins that mediate a variety of transient cell-cell adhesion interactions in the bloodstream.
