Two complementary regions of nucleic acid molecules will bind and form a double helical structure held together by base pairs. In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA.he DNA double helix polymer of nucleic acids, held together by nucleotides which base pair together. In B-DNA, the most common double helical structure, the double helix is right-handed with about 10â10.5 base pairs per turn. This translates into about 20-21 nucleotides per turn.
DNA Structure and Function. 1  Watson-Crick model of DNA; double helix. 2  The double in the double helix means that DNA is found in a double-stranded form - 2 single-stranded chains of DNA stuck to each other via hydrogen bonding of the base pairs.3  The 2 single-strands are anti-parallel to each other. The double in the double helix means that DNA is found in a double-stranded form - 2 single-stranded chains of DNA stuck to each other via hydrogen bonding of the base pairs. 2  The 2 single-strands are anti-parallel to each other. 3  Going from 5' to 3' of one strand means going from 3' to 5' of the other strand.
