Last time I checked its >32%. I can't find the paper in my bookmarks. Mutations lead to more mutations Dok, there is absolutely no way that drift is = 0. Drift rate could be relative to how many mutations you have, which would meant the mesenchymals would drift faster? Obviously the type of mutation also matters, its been a long time but arent reading frame changes from a loss of a nucleotide the worst, just swapping a nucleotide out would lead to an aberrant protein and rarely hit a promoter.
That isn't to say the drift isn't enough to over come DCVAX SAY WHAT?!!
