Anaphase
The area where a pair of chromatids is attached is known as the centromere. It serves as the point of attachment for spindle fibers during cell division, allowing the chromatids to be pulled apart and distributed to daughter cells.
1 centromere for every pair of chromatids
A centromere and a pair of sister chromatids
A bivalent.Sister chromatids are normally joined at the centromere. When homologous chromosomes pair, the two sister chromatids of one chromosome join with the two sister chromatids of the other chromosome. So it is really the joining of non-sister chromatids that is special.The word "bivalent" refers to the temporary combining of the two chromosomes (four chromatids). The bivalent forms in prophase I of meiosis, and is split in anaphase I.
Recall the Wobble-Base - here is a Wobble-Answer: This protein disk is called the di-Chromosome Centromere assembly disk [it brings - and temporarily Locks - the centromeres of the pair of Chromosomes together].

Each pair of chromatids is attached at an area called a centromere.
each pair of cromatids is attached at an area called the Centromere.
During prophase, a chromosome is composed of tightly coiled DNA and protein molecules. Each chromosome exists as a pair of identical sister chromatids which are held together at the centromere.

they're identical because they are the product of replication.
