Abstract
In order to study individual biochemical compounds like proteins, DNA, or RNA, biochemists need to know how to purify these components from a complex mixture. This is especially important for biotechnology and pharmaceutical industries, which sell purified biochemicals as reagents or drugs to consumers. Do an experiment to purify DNA, RNA, or protein from a complex mixture (for purifying DNA, see the Science Buddies project Extracting Onion DNA). The source of the material can be a cell line, bacterial culture, plant extract, or yeast culture. Which purification strategies work best for your compound of interest? Can you use enzymes like protease, DNAse, or RNAse to test the product of your purification to see if it worked? Are there ways of altering the protocol to make it work better and increase the yield? For example, you could try changing detergent concentrations, salinity, or pH, or adding enzymes.Variations

Career Focus
If you like this project, you might want to think about career opportunities in
Biotechnology.
Growing, aging, digesting—all of these are examples of chemical processes performed by living organisms. Biochemists study how these types of chemical actions happen in cells and tissues, and monitor what effects new substances, like food additives and medicines, have on living organisms.
