The description of the secondary structure of DNA double helix is correct, EXCEPT: A. Two antiparallel strands B. Deoxyribose-phosphate frame located outside the strands C. Two strands are joined by hydrogen bond formed between A-T and G-C D. Diameter of helix is 2 nm, and 10 bases in each turn E. Nucleosome is the structural unit of DNA double helix

The shape of DNA is described as a double helix. Click all that apply to the description of DNA. a. DNA is made from a single strand of nitrogenous bases. b. A double helix resembles a "twisted ladder." c. The "backbone" of the ladder is made up of alternating sugar and phosphate groups. d. The "rungs" of the ladder are made up of the bases joined by hydrogen bonds.

The following statements about the double-helical structure of DNA are correct EXCEPT It has adenine paired with thymine and cytosine paired with guanine It can assume many different forms including A-DNA, B-DNA, and Z-DNA In B-DNA, all the hydrogen-bonded base pairs lie in a plane perpendicular to the helix axis None of the above are correct
