Identical copies of chromatin held together by cohesin at the centromere are called ___________. a. histones. b. nucleosomes. c. chromatin. d. sister chromatids.
Madhur L.
1. The DNA of every eukaryotic cell is stored in one or more **nucleus** located in the **chromosomes**. 2. A duplicated chromosome remains tightly paired with its partner at a region called the **centromere**. 3. Chromosomes contain most of the cells **DNA** which acts as the molecules of heredity. 4. Before a cell divides, it copies all of its chromosomes. While the two copies of a chromosome are attached they are called **sister chromatids**. 5. DNA and protein together form a complex called **chromatin**.
Adi S.
In a linear chromosome, sister chromatids are attached or held together by: - Centromeres - Safety pins - Centrioles - Chromosomal clamps
