Which of the following statements regarding DNA is not true? O uracil is paired with adenine O the double strands are antiparallel O it has a negative charge O it has a sugar-phosphate backbone
Added by Rodrigo J.
Step 1
Uracil (U) is a nitrogenous base found in RNA, not DNA. In DNA, thymine (T) pairs with adenine (A). Therefore, the statement "uracil is paired with adenine" is false. The double strands of DNA are antiparallel, meaning they run in opposite directions (5' to 3' Show more…

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

Which of the following statements is not TRUE with respect to the structure of DNA? Select one: a. The two strands that form DNA are complementary and antiparallel to each other b. All options are true with respect to the structure of DNA c. The backbone of DNA is formed by phosphodiester links that binds the 5' end of one nucleotide to the 3' of the next one. d. The alpha helix is the consequence of hydrogen bonds in between the oxygen of one nucleotide and the amine group of a different nucleotide e. The DNA double helix has a constant diameter because each pyrimidine binds complementary to a purine
