The addition of a drug that inhibits GTP hydrolysis in subunits incorporated into the polymer will promote microtubule . The addition of a drug that caps the minus end of the microtubule and prevents subunit exchange at the minus end will promote microtubule . The addition of a drug that promotes GTP hydrolysis in the microtubule will promote microtubule .
