Explanation:
Detailed explanation-1: -21 Why neurons and some other specialized cells divide infrequently? They have been shunted into GO They can no longer bind Cdk to cyclin They no longer have active nucle They no longer carry receptors for signal malecullesl They show a drop in MPF concentration.
Detailed explanation-2: -Unlike most cell types, neurons are believed to have permanently blocked their capacity to proliferate once they are differentiated, being typically found in a quiescent state in the adult nervous system.
Detailed explanation-3: -Also, neurons do not divide due to the absence of rod-like structures called centrioles. These structures are responsible for spindle formation that is necessary for cell division.
