Course Code: Course Title1LABORATORY ACTIVITY 3DNA EXTRACTIONIntended Learning OutcomesBy the end of this activity, you must be able to:1. Extract and visualize crude DNA from plant cells.2. Explain the mechanism of household and kitchen materials for DNAextraction.Deoxyribonucleic acid (DNA) is a nucleic acid that contains the geneticinstruction used in the development and functioning of all known livingorganisms.It contains the codes or instructions needed to construct thecomponents of cells, such as proteins and RNA molecules.In studying DNA, scientist must work with DNA itself outside theprotective walls of the nucleus and cell membrane. Researchers have learnedto separateto isolate DNA from the proteins and other substances in the cell.DNA was first isolated by Swiss Physician Friedrich Meischer in 1869. Now,DNA isolation is one of the most basic and essential technique in the study ofDNA.DNA extraction is a routine procedure to collect DNA for subsequentmolecular or forensic analysis.It is the first step in the analysis andmanipulation of DNA that allows scientists to detect genetic disorders, produceDNA fingerprints of individuals, and even create genetically engineeredorganisms that can produce beneficial products such as insulin, antibiotics andhormones.
