5
Q
What helps to hold DNA double helix together?
A
- H-bonds between pair
- hydrophobic effect of bases on inside and sugar on outside
- bases are stacked to increase Van Der Waals
6
Q
Why does the hydrolysis of phosphoanhydride have such a high delta G value?
A
- They are negatively charged
- Large resonance stabilization
- ADP2- product rapidly ionizes to release a proton into a medium of very low [H+]
