Intro to Genomics


The human body is like a complex piece
of music. Music is made up of notes that tell people how to play the song. Our bodies contain DNA. DNA is arranged into genes, which are the set of instructions that tell our bodies how to function. The complete set of DNA in our bodies is called the genome. In music, the order of notes needs to be correct to play the song. Sometimes when we play music, certain notes are missed, or played at the wrong time. Sometimes this sounds like a mistake. Other times it just sounds a little different and in our bodies the order of DNA needs to be correct for development, function, and growth to happen the way it is supposed to. Likewise with DNA, parts can be lost or changed – something we call a variant. Most DNA variants are harmless but some can cause significant problems.
