How big is the human genome?

I get asked this question a lot. How big is our genetic code? You know… that DNA blueprint thing… consisting of billions of letters… A’s, G’s, C’s, T’s… present in all of the <a href="http://informahealthcare.com/doi/abs/10.3109/03014460.2013.807878" rel="noopener ugc nofollow" target="_blank">TRILLIONS</a> of cells in the human body… the thing that makes you you. How big is it, really? We each have ~3 billion base pairs in our genomes, but how much storage space does one human genome take up? The answer, of course, is: It depends. It depends on what we’re talking about. Are we referring to that single string of letters inside your cells? Or the raw data that comes off a genome sequencer, which has to have many “reads” at each position for adequate coverage, and has quality data associated with it? Or perhaps we’re just talking about the list of every spot in your genome where you differ from the so-called “normal” reference genome? <a href="https://medium.com/precision-medicine/how-big-is-the-human-genome-e90caa3409b0">Read More</a>
