c. When two nucleotides have hydrogen bonds between their bases (base paired), the sugar phosphate backbones are always choose one: (parallel / antiparallel) d. In RNA the purine base A (adenine) pairs with the pyrimidine base (guanine) pairs with the pyrimidine base choose one: (opposite / matched / complementary / dimerized) and the purine base G This is referred to as being

List the nitrogenous bases for DNA vs. RNA, including the complementary base pairs.

Compare and contrast the structure of DNA and RNA.  Be sure to describe each of the three components of a nucleotide for both DNA and RNA along with the types of bonds formed between the components.  In addition, explain: how the nucleotides link together to form each molecule, why the prime ends are labeled 5’ and 3’, what antiparallel is, what phospodiester linkages are and what complementary base pairing is.

Which one of the following statements about nucleic acids is correct? Multiple Choice NTPs can be incorporated into either DNA or RNA molecules, but dNTPs can only be incorporated into DNA molecules A nitrogenous base, 5-carbon sugar, and two phosphate groups would most accurately be referred to as a nucleotide diphosphate. During nucleic acid synthesis, the phosphate group at the 3' carbon of the incoming monomer is covalently linked to the hydroxyl group at the 5' carbon of the existing macromolecule. RNA and DNA have all the same pyrimidine bases in them, but differ in the selection of purine bases. A nucleic acid found in a cell with the sequence GCCTTATCGCG would most likely be found paired with another molecule in double-stranded form.
