Another day another brain fart in Lab Meeting

This is my second lab meeting. In my first lab meeting there was ALOT I told my self I would have to look up. And since I was unfed and exhausted there was a part I missed.

In this lab meeting I kind of fell asleep because the last presenter started talking about neurology. I wasn't seeing the connection except for the fact that there was NFkB in the subject and the fact that HIV infects microglia. But the connection never came they never made it across the bridge so my attention started to move on. I don't even remember what I was thinking about.
All of the sudden the PI interrupts and asks, "Isa, do you know what Chromatin Immunoprecipitation is?" I automatcally answered "No," just because I heard the word Chromatin. Then as she explained it all came back to me, "CHip!" Out of all the things in the world how could I fucked up with CHip?
I have no idea, but it happend. I blushed soooo hard for getting caught like that in the first place. And then I wanted to crush my head on the table when I realized that I already knew Chip
By the way Chip is used to detect if a protein binds to a specific gene or part of a genome, in vivo. Yeah, brain farting here. Can someone shoot me?
