Interpreting DNA sequencing data: answers to the quiz

Which read(s):

  • 1. contain either a SNP (a single nucleotide polymorphism) or a position where different members of a multi-gene family have a different base?
  • C

  • 2. doesn't have any DNA?
  • B

  • 3. is a PCR product?
  • A, B, and C.  All of three reads were obtained by sequencing PCR products, generated with the same set of primers.

Since DNA diagnostics companies seem to be sprouting like mushrooms after the rain, it seemed like a good time to talk about how DNA testing companies decipher meaning from the tests they perform. Last week, I wrote about interpreting DNA sequence traces and the kind of work that a data analyst…

If you've read any of the many stories lately about Craig Venter or Jim Watson's genome, you've probably seen a "SNP" appear somewhere. (If you haven't read any of the stories, CNN has one here, and my fellow bloggers have posted several here, here, here, here, here, and here.) You may be…
Sometimes asking a question can be a mistake. Especially when your question leads to more questions and having to question things that you didn't want to question, and pretty soon you begin to regret ever opening the file and looking at the data and asking the question in the first place. Sigh.…
