centromere
Each pair of chromatids is attached at an area called a centromere.

Centromere
Equator
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.
a centromere?
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.
Centromere
The centrometre
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.
Homologous chromosomes is a pair made of a paternal and maternal chromosomes. But sister chromatid is either pairs of paternal or maternal chromosomes
