Polarity causes DNA polymerase III can only add nucleotides to the 3' end of a DNA strand.

Polarity causes DNA polymerase III can only add nucleotides to the 5' end of a DNA strand

DNA polymerase III can add nucleotides to any random point on a DNA strand regardless of polarity

Hydrogen bonds prevent DNA polymerase III from adding nucleotides to a DNA strand
