Question

The length of one complete turn of a DNA double helix is (A) 34 mathringA (B) 34 nm (C) 3.4 mathringA (D) 3.4 μ m

Tardigrade Admin · Accepted Answer

The DNA molecule has the shape of a double helix. The radius of each helix is about 10 mathringA. Each helix rises about 34 mathringA during each complete turn and there are about 2.9 × 108 complete turns.
