Because of your videos I have managed to make it through my college biology course. I got a 96 on the final test! Thank you!

You are right to point out the importance of protein folding and the critical role of the R groups in directing and stabilizing the fold. For a protein to interact with its specific receptor the target cell, it has to be folded. Unfolded proteins are inactive. Other protein enzymes, isomerases, and foldases are responsible for folding. Some protein folds would take up to a million years if left alone. Foldases can accelerate the fold in as little as microseconds.

Small point. A string of amino acids with less than 20 residues is generally referred to as a Peptide. Greater than 20 AA = Polypeptide, polypeptides connected = Protein. Your video, in the beginning, shows 8 or 7 and you call it a polypeptide.

If DNA requires proteins, such as helicases, to replicate and helicase requires DNA for sequence synthesis, I wonder - What came first?
