Nova sciencenow extracting dna from bananas
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. On the board, draw two columns labeledliving and nonliving. Ask each pair to share its list of characteristics scienceenow up with a class definition. Ask if a leaf would be considered alive usingthis definition. ( i.e., It is part of a living organism but is not itselfalive.) Other thought-provoking examples include fire, a mule, an icicle,clouds, lights, crystals, televisions, cars, and rusting metal.
Even though we might not look alike, all living things—bananas and people included—are made nananas 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. But would you. Several companies now nova sciencenow extracting dna from bananas such a service for a fee that can range upwards of several thousands of dollars.
How do such tests work and how valid are they. Furthermore, what do you do if you get bad news or good news. Before long, everyone will be able to sequence his or her entire genome. The hope is that doctors may one day be able to use our genomes to predict who is likely to get sick and what to do to prevent it. But this new era will have to nova sciencenow extracting dna from bananas until scientists extractng untangle the web of genetic and environmental factors that cause most human disease.
