The centromere is a vital part of the chromosome that serves as the attachment point for spindle fibers during cell division, specifically during mitosis and meiosis. It is responsible for holding sister chromatids together until they are separated into two daughter cells. While telomeres protect the chromosome ends, the centromere ensures that each daughter cell receives the correct number of chromosomes. Options A, C, and D describe functions unrelated to the centromere; A discusses telomeres, C refers to the genetic material itself, and D pertains to the initiation of DNA replication, which occurs at different sites on the DNA molecule.

This option refers to the function of telomeres, not centromeres. Telomeres are structures that cap the ends of chromosomes to prevent degradation.

This is the correct function of the centromere. It is the region where sister chromatids are joined, allowing for proper segregation during cell division.

This option is incorrect as genetic information is carried in the DNA sequence of the chromosomes, not specifically by the centromere.

This option is incorrect because DNA replication is initiated at origins of replication, not at the centromere, which has a different function.
