Nucleoli are comprised of DNA, RNA, and proteins and disappear during prophase of cell division only to reassemble during telophase [5]. In addition, nucleoli consist of two separate parts: the granular component and the fibrillar component. The fibrillar component contains a large quantity of RNA polymerase I, which transcribes ribosomal RNA, and the granular component is where the later stages of ribosome production take place [5]. Besides its function to produce ribosomes, some scientists believe that the nucleolus also plays a role in cell aging [1]; however, this has not been proven. Deoxyribose nucleic acid, also known as DNA, is made up of genetic information contained in smaller repeating nucleotides [6]. DNA determines what proteins need to be produced in the cell and is mainly found in the control center of the cell, the nucleus, for this reason [2]. However, the amount of DNA that each cell contains is too much to fit into the nucleus without being compacted. To compact the double helix of DNA, the double helix wraps around proteins called histones to form chromatin
