D. DNA recognition

Answer

A

Explanation

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