you're uh, assigning just a tad too much power to the well above average biochemist.
More seriously, I think Harry's path here is much more magic than bio focused. He's seen memories removed and copied. If he can figure out how to remove ALL the memories from a body, and if he knows the obliviate charm, and if dead cells work for poly juice (which they should since hair is dead) then he has a decent path using only minor variants to known magic.
Hair isn't even cellular. Given that it can be cut off and used, follicles are not required.
This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 90. The previous thread has passed 750 comments.
There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes.
