The Centromere is where the chromatids are attached to each other.

After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.

1 centromere for every pair of chromatids
Chromatids condense into an X shape before mitosis. Chromatids are identical strands of chromosomes. After duplication there are 12 chromatids that are in 3 pair of homologous chromosomes.
Sister Chromatids
Each pair of chromatids is attached at an area called a centromere.
each pair of cromatids is attached at an area called the Centromere.

Pairs of chromosomes are not attached. Before mitosis chromosomes replicate themselves, these twin identical chromosomes are attached at the centromere. before cell division the cell has 46 chromosomes (23 pairs) but has 2 copies of each individual chromosome called chromatids,(making a total of 92 chromosones, 46 for each daughter cell) which are joined at the centromere giving the characteristic X shape. Pairs are not joined, chromatids are.
After DNA replication, when each chromosome exists as a pair of identical sister chromatids, the sister chromatids are tightly attached to each other at the centromere.
The chromatids are attached to each other at the Centromere. Hope that helps have a nice day.
