nucleotide | the part of the eukaryotic nucleus where ribosomal RNA is synthesized |
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 |
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 |
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 |
