Why did the writer say "sequencing your own DNA"? If you don't follow the guidance, you will get a plain result(your own DNA as a human one)? Did he mean an existing DNA?
ex)Science consists not just of a method, but a body of knowledge and of technique. The established body of textbook knowledge forms a set of constraints(a box, if you will) that the scientist must work within. Any study must obey the conservation of momentum, of energy, and of mass, whether you like it or not. Ignoring physical constraints can lead to failure. There are also constraints consisting of the established methods, procedures, and statistics for a field. These methods have been widely tested and debated over time and accepted as reliable or at least standardized. For example, for DNA studies there are lab procedures to guard against cross-contamination. If you ignore this guidance you may end up sequencing your own DNA instead of that of the target organism.
