WebJul 28, 2024 · For example, we observe chromatin chains with short linear segments of what appear to be stacked nucleosomes (Fig. 5D, arrows). There are chromatin chains with distinct helical twists ( Fig. 5E ). There are also numerous instances of chromatin chains that converge and interact closely for short sections. WebThe dynamic nature of chromatin is regulated by enzymes. For example, chromatin can be loosened by changing the position of the DNA strands within a nucleosome.
