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 |
Base sequence | The order of nitrogenous bases on a chain of DNA |
Complementary base pair | The nucleotide bases in a strand of DNA or RNA that are paired with those of another strand; adenine pairs with thymine or uracil, and guanine pairs with cytosine |
Deoxyribose | A five-carbon sugar that is a component of DNA nucleotides |
Nitrogenous base | An organic base that contains nitrogen, such as purine or pyrimidine; a subunit of a nucleotide in DNA and RNA |
Nucleotide | In a nucleic-acid chain, a subunit that consists of a sugar, a phosphate, and a nitrogenous base |
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 |
Pyrimidine | 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 |
