RNA extraction, as shown in the image, involves multiple steps to isolate purified RNA from biological samples. The process includes the following key steps: 1. Cell Lysis • Lysis buffer is added to the sample (e.g., 30 mg of liver, gills, brain tissue). • The sample is homogenized and centrifuged to break open cells and release RNA. 2. Centrifugation • The mixture is centrifuged to separate cell debris, forming a pellet at the bottom. • The supernatant containing RNA is carefully...
