DNA duplicates chromosomes that are connected at the centromere. They are usually connected through the kinetochore-microtubule which happens during the process of mitosis.
Sister chromatids are held together by a protein complex called cohesin, which forms a ring-like structure around the two chromatids. Cohesin binds to specific DNA sequences on the chromatids and helps in ensuring that they are properly aligned and segregated during cell division.
At the beginning of meiosis, copies of chromosomes linked together at their centromeres are called sister chromatids. These sister chromatids are duplicated copies of a single chromosome and are held together by proteins called cohesins.
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.
Sister chromatids are held together by a protein complex called cohesin, which forms a ring-like structure around the two chromatids. Cohesin binds to specific DNA sequences on the chromatids and helps in ensuring that they are properly aligned and segregated during cell division.
Chromatin arms are hold by centromeres.
The sister chromatids are held together by the centromeres. Each chromosome is made up of two sister chromatids.
