Question

Quizplus · Accepted Answer

The structures that line up the chromatids on the equatorial plate during metaphase are the microtubules, specifically the polar and kinetochore microtubules. Asters refer to the microtubules that extend from the centrosomes and do not play a direct role in chromosomal alignment. Centrosomes and centrioles are involved in spindle formation but do not directly line up the chromatids on the equatorial plate. Histones are not directly involved in chromosomal alignment.
