A)hold sister chromatids together.
B)ensure that proper chromosome arm length is maintained.
C)allow easy karyotyping.
D)develop meiotic chromosome replication.

Question

Quizplus · Accepted Answer

The centromere is responsible for holding the sister chromatids of a chromosome together. During cell division, the spindle fibers attach to the centromere and pull the sister chromatids apart to opposite poles of the cell. If the centromere fails to hold the sister chromatids together, then the chromosomes can undergo improper segregation which can result in chromosomal abnormalities.

B, C, and D are incorrect choices. The centromere is not responsible for maintaining proper chromosome arm length or allowing easy karyotyping. Additionally, the development of meiotic chromosome replication does not involve the centromere.
