WebThe two copies of a chromosome are called sister chromatids. The sister chromatids are identical to one another and are attached to each other by proteins called cohesins. The attachment between sister chromatids is tightest at the centromere, a region of DNA that is important for their separation during later stages of cell division. WebShort answer: Chromosomes are “made of” DNA and histones (proteins). During DNA condensation (packing, coiling), the process is aided by chaperone proteins, but these are not permanent parts of the chromosome proper.
