what differentiates the third structure form the other two?
It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form.
Z-DNA
It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form.
the structure found in the cell that contains strands of dna is called a(n) nuclei what is its full form? Deoxyribonucleic acid what is base pairing? In a DNA double helix, each type of nucleobase on one strand bonds with just one type of nucleobase on the other strand, his is called complementary base pairing. are there any alternative structures? Yes, DNA exists in many possible conformations that include A-DNA, B-DNA, and Z-DNA forms how is it replicated? The two strands are separated and then each strand's complementary DNA sequence is recreated by an enzyme called DNA polymerase. what is the biological function of the first alternative structure mentioned above? A-form DNA is believed to be one of the adaptations of hyperthermophilic archaeal viruses to harsh environmental conditions in which these viruses thrive.

Z-DNA [SEP] Introduction
Z-DNA is one of the many possible double helical structures of DNA. It is a left-handed double helical structure in which the helix winds to the left in a zigzag pattern, instead of to the right, like the more common B-DNA form. Z-DNA is thought to be one of three biologically active double-helical structures along with A-DNA and B-DNA.
