HOW TO SEQUENCE YOUR DNA FOR <$2K

The first human genome took $2.3 billion and 13 years to sequence. It now takes an Oxford Nanopore to sequence whatever DNA you want in less than 48 hours. The machine uses electrical nanopores to read the individual charge of each DNA base pair. It costs $1,000, making it possible to sequence your own DNA at home for around $1,100. Using the machine can help people avoid giving their DNA to companies and risking it being lost in a data breach.
