This document outlines the process and components used to extract DNA from cells. It first discusses the components needed, including detergents, chelating agents, buffers, and solvents to disrupt membranes, inactivate DNases, precipitate DNA, and remove contaminants. It then provides a 7-step protocol involving grinding tissue, lysing cells with CTAB buffer, purifying DNA with chloroform/isoamyl alcohol and isopropanol precipitation, washing with ethanol, and resuspending the DNA in TE buffer. The overall process disrupts cells and membranes, isolates the genetic material DNA, and purifies it for downstream applications.
