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.
Each strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases. This is critical when cells divide because each new cell needs to have an exact copy of the DNA present in the old cell.DNA is a double helix formed by base pairs attached to a sugar-phosphate backbone.DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a personâs body has the same DNA.ach strand of DNA in the double helix can serve as a pattern for duplicating the sequence of bases.
