Spindle Fibers (Microtubules)attach to a Chromosome's _______ During Mitosis

Question

Spindle fibers (microtubules)attach to a chromosome's _______ during mitosis.
A) centromere
B) telomere
C) genomere
D) euchromatin
E) tips

Accepted Answer

Spindle fibers attach to the centromere, a specialized region on the chromosome, during mitosis. This allows the spindle fibers to pull the chromosomes apart during cell division. Telomeres are located at the ends of chromosomes and are not involved in attachment to spindle fibers. Genomere is not a scientific term, and euchromatin refers to the less condensed, actively transcribing regions of chromatin, which are not directly involved in spindle attachment. Tips could refer to telomeres, but as mentioned, they are not involved in spindle attachment.
