Webcell diagrams for both plants and animals. A complex double-layered barrier made of lipids, proteins, and carbohydrates, the plasma membrane is fluid, highly dynamic, and double-layered. The membrane plays crucial functions in cell adhesion, cell-to-cell communication, and cell shape, as well as in the movement of chemicals within and outside of the cell. WebIf the breaks occur on different chromosome arms the inverted section includes the centromere and the result is a per i centric inversion (peri = around). No genetic material has been lost in this rearrangement. Figure 5.2. 3 c: Duplications can occur from when DNA breaks at different places in sister chromatids.
