DNA is a polar molecule because it has a negatively (-) charged phosphate group attached to the 5' end of the molecule and a negatively charge hydroxl group (OH) attached to t â¦ he 3' prime end of the molecule. Thus, it is a POLAR molecule which allows it to interact in an aqueous environment.NA is a polar molecule because it has a negatively (-) charged phosphate group attached to the 5' end of the molecule and a negatively charge hydroxl group (OH) attached to t â¦ he 3' prime end of the molecule.
If DNA wasn't negatively charged, the structural fundamentals of interactions between DNA and transcription factors would be completely different. Thanks to the fact that it is negatively charged, it becomes spontaneously pretty straight when denaturalised, because negative charges repel themselves. It forms very wide curves. And of course, histones wouldn't be able to join DNA and exert their key regulating functions.
