The Attachment Point on the Chromosome for Spindle Microtubules Is

Question

The attachment point on the chromosome for spindle microtubules is the:
A)telomere.
B)centromere.
C)origin of replication.
D)sister chromatid.
E)allele.

Accepted Answer

The attachment point for spindle microtubules is the centromere. The centromere is a constricted region of a chromosome that plays a critical role in chromosome movement during cell division. Spindle microtubules attach to the centromere via protein structures called kinetochores and pull the chromosomes apart during mitosis or meiosis. The other answer choices are not directly involved in spindle microtubule attachment.
