Barcode Fruit Genome

After some research into persimmon fruits, I discovered a barcode system used to identify the genome of Diospyros persimmon fruits. This barcode system is used widely to help identify species of fruits, herbs, etc. and it is an excellent method to store DNA in a barcode system. {genius}

In 2003, researchers at the University of Guelph in Ontario, Canada, proposed “DNA barcoding” as a way to identify species. Barcoding uses a very short genetic sequence from a standard part of the genome the way a supermarket scanner distinguishes products using the black stripes of the Universal Product Code. Two items may look very similar to the untrained eye, but in both cases the barcodes are distinct.

Almost every cell in your body is loaded with molecules called DNA. Each DNA molecule is made of chemicals called “bases” nicknamed A, T, C, and G for adenine, thymine, cytosine, and guanine. The bases occur in pairs, organized into a twisting, ladder-like structure, the famous “DNA double helix.” The ordering of the base pairs in the helix creates a set of instructions that are the blueprints for you to grow and live. The whole set of instructions is your genome.

Sections of your genome (genes) tell your cells what proteins to make. Each protein plays a distinct role, such as the protein keratin that makes fingernails strong or the protein crystallin that makes the lens of your eye transparent. Protein manufacture is the foundation for a living being. Your genome is unique to you and determines what traits you have. Many traits are determined by more than one gene, in some cases by tens or hundreds of genes.
