| Question | Answer |
|---|---|
| Nucleotide | in a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base |
| Deoxyribose | a five-carbon sugar that is a component of DNA nucleotides |
| Nitrogenous base | an organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA and RNA |
| Purine | a nitrogenous base that has a double-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; either adenine or guanine |
| Pyrimidline | a nitrogenous base that has a single-ring structure; one of the two general categories of nitrogenous bases found in DNA and RNA; thymine, cytosine, or uracil |
| base-pairing Rules | the rules stating that cytosine pairs with guanine and adenine pairs with thymine in DNA, and that adenine pairs with uracil in RNA |
| Complementary Base Pair | the nucleotide bases in one strand of DNA or RNA that are paired with those of another strand; adenine pairs with thymine or uracil, and guanine pairs with cytosine |
| Base Sequence | The order of nitrogenous bases on a chain of DNA |
