The dJ/dS Ratio Test Reveals Hundreds of Novel Putative Cancer Drivers.

abstract：:A 32-kb region including the Adh structural gene was analyzed with six restriction endonucleases in 20 lines of Drosophila pseudoobscura, one line of D. persimilis, and one line of D. miranda. Nineteen lines of D. pseudoobscura from a single population were estimated to be polymorphic at one in every 15 nucleotides (p...
