Web25 feb. 2024 · Figure 1 Chromatin structural organization during interphase and mitosis.(A) Levels of chromatin structural organization. At the most basic level, an histone octamer makes a nucleosome with ~147 bp of DNA resembling a beads-on-a-string structure, which is then folded with neighbouring nucleosomes to make a chromatin fiber. WebDuring interphase of a cell cycle, the cell copies DNA, grows, and carries out its normal functions. The cell cycle refers to the cycle that has cells reproduce and divide. The cell cycle is divided into two or three main phases: interphase, mitosis, and cytokinesis. What exactly happens in the interphase of a cell cycle?
