DNA duplicates chromosomes that are connected at the centromere. They are usually connected through the kinetochore-microtubule which happens during the process of mitosis.

The sister chromatids (arms) are held together by centromeres. Centromeres are the site of attachment for the spindle fibers.
The centromere is the part of a chromosome that links the sister chromatids together. There are two types of centromeres. Regional centromeres have DNA sequences that contribute to, but do not define function. Point centromeres are smaller and more compact, but the DNA sequences are necessary and sufficient to specify the centromere's identity and function.

No, the centromere only serves to hold two sister chromatids together.
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
Chromatin arms are hold by centromeres.

Copies of chromosomes linked together at their centromeres at the beginning of meiosis are appropriately called sister chromatids. Chromosomes are found in cells.
The hydrogen bonding across to the nitrogen's lone pairs in each match is strong enough in a correctly matched pair to hold the DNA molecules together.
