The centromere is a constricted, pale staining structure containing kinetochore microtubules (protein complex). Again, the chromatid connects at the centromere,.Each chromosome gives closely apposed, identical halves (chromatid or sister chromatid),.The chromosome becomes oriented in the equatorial plane perpendicular to the centrosome,.Metaphase under a light microscopeĭuring the metaphase of the mitosis cell division, you will find the below-mentioned essential features – In this prometaphase stage of mitosis cell division, the movement of the chromosome is highly dynamic. Finally, the spindle can attach to the arms of the chromosome. They anchor the mitotic spindle in the center of the cell.Īgain, the kinetochore microtubules grow from the poles and attach to the chromosome. The astral microtubules grow from the poles to the plasma membrane. You will see 3 types of microtubules in this stage – astral, kinetochore, and spindle microtubules,.
