                Microtubule is involved in the:                                                      

    A)                                                                         cell division

    B)              DNA recognition

    Correct Answer: A

    Solution :

                Microtubules are one of the essential protein filaments of the cytoskeletons of probably all eukaryotic cells and of their cilia, flagella, basal bodies, centrioles and mitotic and meiosis spindles. Each microtubule is made up of a hollow cylinder of 13 pro to filaments of the tubulin protein. The diameter of each microfibril is 25 nm. The function of microtubule is to guide organelle and chromosome movement in die cell, cause cell elongation and help in movements of cilia/flagella.
