Kiwifruit dna extraction results
PROBLEM: How does the different fruit differentiate the amount of DNA extracted. Science Cafe. Imagination Station. For more thorough analytical work, you need more control over the components of your chemicals, and it may be worth investing in a kit from one of the major suppliers. This is a rough and ready method that should give reasonable quantities of DNA from quite large quantities of material.Lesson organisationYou can run this as a demonstration, or as small group work.
Or you could prepare enough of each of several materials to allow groups to take samples from which they extract the DNA.Apparatus and Chemicals. Extracting DNA from a kiwi fruit. DNA is the polymer of life, storing the information that makes all living things what they are, from us humans to the humble kiwi fruit. You could even go into more detail and explain some of the concepts of genetics to older children.During a busy science fair there might not be time to wait 20 minutes forActivity 1 - DNA ExtractionWe will extract DNA from fruit to investigate how it looks and feels.
This procedure is similar to what scientists have to do before they can use the information contained in this DNA. Students will be able to demonstrate the experiment through following directions and procedures. As a basis for understanding this concept and addressing the content in the other three strands, students should develop their own questions and perform investigations. Students will. The student holding the pipette will slowly squeeze the pipette, releHow to Extract DNA From FruitsHow to Extract DNA From FruitsG.
Carboni, January 2007Text editing by Donald Desaulniers, Ph.D.CONTENTSINTRODUCTION PROCEDURE Summary of the procedure Preliminary operations Preparation of the extracting solution Preparation of the mush Extracting the DNA Filtration Removing the proteins Precipitating the DNA Observation through the microscope CONCLUSION REFERENCESFigure 1: Test tube with DNA extractINTRODUCTIONIn recent years, it is not uncommon to read articles on DNA in bothscientific and popular magazines.
DNA is regularly mentioned in the news and isoften featured in TV detective or crime-scene investigation dramas. DNA, alsoknown as DeoxyriboNucleic Acid, is a long molecule that holds the geneticinformation for all living beings, be it vegetable, animal or a simplemicroorganisms. It is capable of copying itself and can synthesize RNA (RiboNucleicAcid).
