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.
Proteins of DNA Replication. 1  DNA Helicases-These proteins bind to the double stranded DNA and stimulate the separation of the two strands. 2  DNA single-stranded binding proteins-These proteins bind to the DNA as a tetramer and stabilize the single-stranded structure that is generated by the action of the helicases. The DNA molecule is unwound and prepared for synthesis by the action of DNA gyrase, DNA helicase and the single-stranded DNA binding proteins. 2  A free 3'OH group is required for replication, but when the two chains separate no group of that nature exists.
