- Some plants have a hard, cellulose layer protecting them. This hardened layer will prevent the detergent from breaking down the cell wall. Can you think of another way to break open the cells? Note: The cell lysis and mashing the fruit with your hands or using a blender helps homogenize the DNA. Homogenization is the process of releasing DNA from the nuclei of the cells by breaking apart the cell walls, plasma membranes and nuclear envelope. It also helps to create a uniform mixture.why is it more advantageous for the cell to have its DNA fused to the cell wall as opposed to dispersed freely in the cell?1. Why were nuclei being unstained when you used eosin? 2. What is the relationship between heterochromatin and the synthetic activity of DNA? 3. What is the significance of using different histological stains? 4. Aside from H&E, what other staining methods are applicable in Golgi apparatus, mitochondria, and nucleic acid?
