MOLECULAR BIOLOGY QUESTIONS AND ANSWERS 100% CORRECT) LATEST () (VERIFIED ANSWERS) What are the 4 broad categories of cellular adhesion molecule - ANS-Integrins - Immunoglobulins superfamily (N-CAM, PE-CAM, V-CAM) - Cadherins - Selectins How many type of subunit do integrins have - ANS-2, alpha and beta Why are they called Immunoglobulin superfamily of cellular adhesion molecules - ANS-Because these CAMs are structurally similar to immunoglobulin What 2 types of binding are immunoglobulin cellular adhesion molecules involved in - ANS-1) Homophilic binding : binding to the same type of molecule 2) Heterophilic binding : binding to different types of molecules, binding occurs om adjacent cell surfaces to trigger cellular cellular responses The passage of a cell through the stages of the cell cycle is controlled by protein kinases that phosphorylate many different proteins at appropriate times. What are these protein kinases called? - ANS-Cyclin-dependent kinases Appropriate cyclin dependent kinases are synthesized at the start of each phase of the cell cycle and destroyed before the cell proceeds to the next phase: true or false?
