Which of the following is true of DNA but not RNA?

Which statement most accurately describes the ‘backbone’ of DNA? Group of answer choices The DNA strand is wound up around histone groups which gives the backbone structure to the chromosome The sugar group from a nucleotide is connected to the next sugar group via a phosphate group The hydrogen bonds between nucleotides are quite strong and provide structure to DNA. Adenine and Thymine, and Guanine and Cytosine are linked together

Which of the following correctly describes the structure of DNA? strands of phosphate-nitrogen backbone, which complementary nitrogenous base pairs bound in a double helix strands of sugar-nitrogen backbone, with complementary deoxyribose base pairs bound in a double helix strands of phosphate-sugar backbone, with complementary nitrogenous base pairs bound in a double helix strands of phosphate-sugar backbone, with complementary nitrogenous base pairs bound in a single helix

CYTOSINE PURINE PHOSPHATES NITROGENOUS BASES PYRIMIDINE SUGARS THYMINE URACIL Alternating deoxyribose and form the backbone of DNA structure, and the are stacked like rungs inside. A purine always pairs with a ; Adenosine always pairs with and Guanine pairs with
