Editing Banana DNA (section)

== Why This Works ==

'''DNA''' stands for '''D'''eoxyribo'''N'''ucleic '''A'''cid. DNA is your body's instruction manual for living - it's a molecule that stores information on everything about your body. DNA is made up of four different building blocks called base components. These components are ''Adenine'' ('''A'''), ''Cytosine'' ('''C'''), ''Guanine'' ('''G'''), and ''Thymine'' ('''T'''). '''A''' and '''T''' can bond, and '''C''' and '''G''' can bond, which creates two kinds of ''Base Pairs''. These base pairs can then bond with other molecules, like sugar molecules and phosphate molecules, to make a ''Nucleotide''. Nucleotides string together to form ''Genes'', which link together to create our ''Chromosomes''. All the chromosomes in your body are collected into a single ''Genome'' that is made up of about three billion base components, and that genome is our DNA! 

Almost all of your cells contain two copies of your full genome. This is because your DNA is coiled up in your cells, and it twists into a shape called a ''double-helix''. If you unwound it all, it could stretch almost six feet! The double-helix shape of the DNA makes it easy to duplicate. Since '''A''' and '''T''' can only bond with each other, and '''C''' and '''G''' can only bond with each other, your DNA can split down the middle, and then each side can replicate the other. A way to think of it is if you were making a peanut butter and jelly sandwich. If your sandwich has only peanut butter, then you know that it needs the jelly. Likewise, if only has the jelly, then you know it needs the peanut butter! When a cell dies, a nearby cell will split its DNA and separate into two cells. Then each cell can recreate the other half of their DNA by seeing what is missing!

Almost every type of living creature on Earth uses DNA, just like humans. It's the information stored in the DNA that causes differences between organisms and species. You get your DNA from your parents - whatever information their DNA held is passed onto you. This is called ''genetic inheritance''. About 99% of your DNA is the same as mine, and every human being; we all have almost exactly the same DNA. It's the small differences in your DNA that give people different eye colors, hair colors, skin colors, heights and other unique traits. Your DNA is what makes you so unique!
