He was taught a course on Linear Algebra and a student ran through the lecture hall in an ape suit (must have been around the time of Halloween). He was took it all in stride.. made a pithy comment and continued with the lecture!

Then I got the answer that they self -assemble (when the necessary conditions are met, I assume). I consider the primordial soup a pretty interesting place. Especially the early days :-D

The reaction is not balanced without it, even when assuming H2O as a by-product. Compare it with the slide she shows a few minutes later, there the C is indeed included. Can someone confirm?

    Hi there , In my understanding point when we have a solution that contains water as its solvent and we also have Hydrophobics molecule ( for example inside cell we have protein and water ) , Hydrophobics substances ( some proteins) tend to combine with each other as they do they release water molecule ( due to Hydrophobic effect ) , and if we trying to fold protein to the shape which matches with its function our solvent is water so there will be certain too much (Ionic & Hydrogen)bonds which is unnecessary , so due to Hydroponic interaction we are trying to get ride of those unnecessariness ( and as a result we release water ) . Hope u get it
