A cell is made up of many parts which include the cell membrane, organelles, and cytoplasm. DNA, which stands for deoxyribonucleic acid, is also found inside of a cell. DNA is found in the nucleus of plant and animal cells. DNA contains the blueprint for development, survival, and reproduction. It is made of nitrogen containing bases which are paired through hydrogen bonds; adenine, thymine, cytosine, and guanine. The phosphate group and ribose sugars make up the DNA. In this lab we extracted our DNA by swishing a salt water solution, which was polar, in our mouths to collect cells. After we swished the solution around, we added detergent to break down the phospholipid bilayer. Alcohol was then added because it is non polar. After the alcohol
