2. match holder polynucleotides of bass, by H-bond.Two parallel wires, and the direction of the opposite (antiparallel).A pair of bass between the A-T (2 H-bonds), C-G (3 H-bonds) = complementary basepairs (bass is base pair is A pair with the cooperative with bond, hydrogen bond, and T 2 G pairs with C bond, hydrogen bond 3.)2. a circular spiral wire to the right (right handed double helix strand)Each pair of bass apart 3.4 angstrom (.34 nm) tilt angle 36° 1 round = 10 pairs = 34 Angstrom base diameter 20 Angstrom.The structure of DNA contains enough new wokli 2-wire video tide Lee fit Lee tide each nucleotide is composed of units called nucleotide tide and long strings. Paula Lee nucleotide tide 2 wires are bonded by hydrogen bonding between the base. Each nucleotide tide. The bond between the phosphate groups occurred without nucleotide tide with 3 positions of carbon sugar nucleotide to another one, so the tide line structure nucleotide polymer tide is. Connect the switch between a sugar phosphate group by one. Direction from the end of the 5 ' to the 3 ' end. The other one is on the line at the end of the first 5 ', so when it happens to distinguish the two strings of DNA that separate the sections with a different direction.
