Hey, your videos are amazing. I find them really helpful, I've been using them as catch up for my biology class that I just joined, and they are absolutely perfect. I was wondering if there is anything similar for chemistry HL as well. Thank you
Guanine and Cytosine Base pair has three hydrogen bonds,because the exocyclic NH2 at C2 on Guanine lies opposite to,and can hydrogen bond with,a carbonyl at C2 on Cytosine
literally studying for my exams using your videos
Your videos have been so helpful! I'm studying for the final exams now and your videos have been a tremendous help! Thank you for making them!
