Never mind the nucleic acids, your presentations deserve far greater attention. Thanks for all of them. I have learned a lot that I missed in high school.
Love the video (love your videos in general - we need short clear snippets for our students!), one tiny issue...the phosphates do not bond together, they attach to the 3' OH of the sugar of the next nucleotide, making for a sugar-phosphate-sugar-phosphate backbone. Please fix so that I can use this with my students :)
I made a basic (no pun intended) video on acids a bases about a month ago, however, it doesn't go into detail about pH, pOH, and hydronium concentrations. Hopefully I will make that video in the next few months.
