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.
Thus DNA replication produces two identical, double helical molecules, enabling genetic information to be copied and passed on from a cell to its daughter cells and from a parent to its offspring. â¢ During replication, the two strand of a DNA double helix are pulled apart to form two Y-shaped replication forks.hus DNA replication produces two identical, double helical molecules, enabling genetic information to be copied and passed on from a cell to its daughter cells and from a parent to its offspring. â¢ During replication, the two strand of a DNA double helix are pulled apart to form two Y-shaped replication forks.
