Explanation:
Detailed explanation-1: -This complex is called chromatin and is formed when the DNA wraps around nuclear proteins and then wraps around itself multiple times to condense the DNA into a smaller volume. Additionally, DNA chromosomes are often recognized and depicted as X-shaped structures.
Detailed explanation-2: -DNA condenses and coils into the familiar X-shaped form of a chromosome only after it has replicated. Because DNA has already replicated, each chromosome actually consists of two identical copies. The two copies are called sister chromatids. They are attached to one another at a region called the centromere.
