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.
Lesson Summary. Let's review what we've learned so far. DNA helicase is the enzyme that unwinds the DNA double helix by breaking the hydrogen bonds down the center of the strand. It begins at a site called the origin of replication, and it creates a replication fork by separating the two sides of the parental DNA.esson Summary. Let's review what we've learned so far.
