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.
Antiparallel DNA has the two strands organized in the opposite polarity, with one strand oriented in the 5â²-3â² direction and the other oriented in the 3â²-5â² direction.est Answer: Double-stranded DNA is a right-handed helix formed by two individual DNA strands aligned in an antiparallel fashion (a right-handed helix, when viewed on end, twists clockwise going away from the viewer).
