You have no clue what you are talking about.
Human Genome project is an example of complete DNA sequencing while 23andMe only tests for specific variations at specific loci. 23andMe and similar companies use commercially available solutions like DNA microarrays [1] with probes preprogrammed [2] for specific target variations and they cannot "read" arbitrary DNAs.

- vaxdigitalnh 14y agoThis is why I often feel it is an utter waste of time to read HN. Alas, people like you are not always around to correct people like Mr. Welch and reign in the ignorance. God only knows how many readers will read comments like his and think he actually does know what he's talking about. They might even rely on name recognition or "karma" to ascertain the validity of his statements. Sad.
