400
An interaction that forms when a hydrogen atom covalently bonded to one electronegative atom is also attracted to another electronegative atom.
What is Hydrogen bond?
500
Interactions that are weak by themselves, but when they occur among many molecules of water, they allow it to stay liquid at room temperature.
What are hydrogen bonds?
500
A macromolecule that has a sugar, nitrogenous base and a triphosphate. It acts as a building block for DNA and RNA.
