How Nanopore Sequencing Is Revolutionising Biology When the first human genome was sequenced completely, it cost an estimated $450 million[i]. Now, thanks to incredible technological advances, just 20 years later we can sequence the entire DNA of a human (foetus or octogenarian) for $600[ii], a cost that is
