Purely from a technical standpoint I'm wondering what you're referring to here. Most of my work is DNA sequencing using different techniques and while we can do it blisteringly fast if necessary it still takes at minimum a few hours to isolate dna, prep the dna for sequencing and then running for 24 hours followed by data analysis. That's for bacterial DNA, I don't have experience with sequencing human genomes but I imagine it is more complicated than bacteria. But, I haven't kept up with literature on this subject lately so now I'm wondering if I've missed some breakthrough technique that speeds up the process to minutes.
