| Term | Definition |
|---|---|
| in a nucleic-acid chain, a sub-unit that consists of a sugar, a phosphate, and a nitrogenous base | nucleotide |
| a five-carbon sugar that is a component of DNA nucleotides | deoxyribose |
| an organic base that contains nitrogen, such as a purine or pyrimidine; a subunit of a nucleotide in DNA and RNA | nitrogenous base |
| 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 | purine |
| 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 | pyrimidine |
| the rules stating that cytosine pairs with guanine and adenine pairs with thymine in DNA, and that adenine pairs with uracil in RNA | base-pairing rules |
| 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 | complementary base pair |
| the order of nitrogenous bases on a chain of DNA | base sequence |
