Which of the following is NOT TRUE concerning the structure of DNA? The two strands of a double helix have identical nucleotide sequences but are organized with opposite polarity The two strands of a double helix are held together by hydrogen bonds between the nitrogenous bases on each strand DNA is negatively charged at neutral pH because of the negatively charged oxygen atoms of the phosphate groups. The sugar group found in DNA is 2'-deoxyribose Individual strands of DNA contain A, T, G, and C nucleotide subunits

All of the following are true of DNA EXCEPT: DNA is a double helix that consists of two antiparallel strands. DNA is a polymer of nucleotides. DNA has a sugar-phosphate backbone. DNA contains the nitrogenous bases adenine, guanine, thymine, and cytosine. The two strands of double-stranded DNA are held together by hydrogen bonds.
