For spindle microtubules, the plus ends are in the center of the spindle and the minus ends are at the spindle poles. Motor proteins move along microtubules walking either toward the plus end or minus end. Given what you know about chromosome movement and spindle changes, predict which type of motor proteins would be present or mediate movement and provide a brief explanation.
