tv and electronic media have increased stress levels

UpdatedJune 13, 201.Extracting DNA from a banana may sound like a difficult task, but it is not very difficult at all. The process involves a few general steps which include mashing, filtration, precipitation, and extraction. You should try not to create bubbKey conceptsCellsDNAGenesFrom National Science Education Standards: Reproduction and heredityIntroductionWhat do you have in common with a banana. Even though we might not look alike, all living things—bananas and people included—are made up of the same basic material.Just like houses are made up of smaller units such as bricks, all living things are made up trillions of microscopic building blocks called cells.

It holds a stringy substance called DNA, which is like a set of blueprints, or instructions. DNA contains a code for how to build a life-form and put together the features that make that organism unique. With a pure sample of DNA you can test anewborn for a genetic disease, analyze forensic evidence, or study a gene involved in cancer. Try thisvirtual laboratory to perform a cheek swab and extract DNA from human cells.

Activity 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. 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).
