The exponential increase in genomic sequencing has shown how little we actually understand about what each gene does , we have the sequence but we do not have it . However , new gene knock - out techniques may reveal the information that is missing ; by " knocking out " ( blocking a gene to stop it from doing ) The genomics revolution means that what ten years ago a small team of researchers could achieve in a year, a PhD student can now do in a week. each gene in turn and health screening each individual , we can finally start to understand the meaning behind the DNA we have been reading .
