Introduction to genetics. For other uses‚ see DNA (disambiguation). The structure of the DNA double helix. The atoms in the structure are colour-coded by element and the detailed structure of two base pairs are shown in the bottom right. The structure of part of a DNA double helix Deoxyribonucleic acid (DNA) is a molecule that encodes the genetic instructions used in the development and functioning of all known living organisms and many viruses. DNA is a nucleic acid; alongside proteins and carbohydrates

Title Application of DNA Barcodes to Identify Various Plant Species Abstract In this experiment we applied barcodes to plants in order to identify what species they are classified under. We also compared the DNA sequences of different plant species using the ribulose-biphosphate carboxylase gene (rbcL). We took samples from a plant called Chard and performed PCR‚ DNA amplification and quantification and sequenced the DNA. During the experiment‚ we hypothesized that this year’s “nonspinach”

Associate Program Material DNA Worksheet Answer the following in at least 100 words: Describe the structure of DNA.DNA is thread formed by two strands‚ related together to form a double helix. The double helix looks like a twisted ladder. The sides of this ladder are long unites called nucleotides and are made of three parts; a nitrogenous base‚ a sugar‚ and a phosphate group. The sides of the ladder or the nucleotides from the two separate strands of the DNA are attached by an appendage

DNA fingerprinting is a way of identifying a specific individual‚ rather than simply identifying a species or some particular trait. It is also known as genetic fingerprinting or DNA profiling. As a technology‚ it has been around since at least 1985‚ when it was announced by its inventor‚ Sir Alec Jeffreys. DNA fingerprinting is currently used both for identifying paternity or maternity and for identifying criminals or victims. There is discussion of using DNA fingerprinting as a sort of personal

New York Mayor‚ Michael Bloomberg‚ has taken the first step to bring American portions back down to reasonable volumes. In passing a law banning sugary drinks over 16 ounces‚ he attempts to lower obesity and related health problems. The Federal Government should follow New York City ordinates and ban high sugar drinks over 16 ounces for the benefit of American health. Drinks high in sugar need to be limited in portion sizes because the rate of consumption is exceeding the amount one’s body can healthfully

Title: Benedict ’s test for Reducing Sugars Testable Question: Are all carbohydrates reducing sugars? Hypothesis: If the carbohydrate contains available ketone or aldehyde molecules then they are reducing sugars. Variables: a. Independent: Function groups react w/ reagent b. Dependent: Color change (red‚ orange‚ yellow) Control: Water Materials: - 4 mL of each solution (Water‚ Starch‚ Glucose‚ Maltose‚ Sucrose‚ Onion Juice‚ Potato slice‚ Milk) - 8 test tubes
