Think of it as a spiral staircase. If you were to dangle a rope over the rail it is certain that it will touch rail again but at a lower section of the spiraling stair case. In DNA, this 'rope' is the force of attraction he mentions, which is hydrogen bonding aka positive force. Might be 5 years late but hope this helps others that stumble upon this same question!
Hi, Great video! I just wanted to let you know that you've accidently drawn 3 bonds on the A-T structure (at time 2:23). Otherwise, it's good and thanks for the review!
Thank you!!!!!!!! Your videos are amazing! Thank you very much, because only reading or writing I was feeling lost. Thank you! Please, continue making videos! :D

I wish I could have the paper you used to make this video. Such a good and organized explanation!
thank you , so much , you don't know how much you helped us , keep up with the amazing job
i dont understand the base staking clearly !

Are you sure, it should work, try again, and let me know please.

You do such an amazing job Thank you
Tnxxx , was really helpful,keep up the good work
Very good explanation, thank you :D
Great video. explanation of forces was really helpful!
thank you for best lecture...clear explanation
If phosphates overcome negative charges of nucleosides, then why DNA molecules are negatively charged ?
Maybe I'm wrong but the Tyrosine molecule has the wrong number of hydrogens at the Hydrogen to carbon bond where it should be H2 instead of just H...
I'm a bit confused at 2:37. Shouldn't the adenine and thymine have 2 hydrogen bonds. It looks like they have three. Great video...
Yeah its a mistake. It should only have 2 hydrogen bonds
Why DNA dangling bases are required
awesome video, explained really well. Thank You
Wow nice ! Excellent! Thanks
THanks! It helps! At the end, the bell rings>
Great video, thanks!
sorry, no....all I get is the red 'x' in top left.. (file ends in "edit" although I doubt that has anything to do with the upload?)
