a five-carbon sugar that is a component of DNA nucleotides
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
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
base sequence
the order of nitrogenous bases on a chain of DNA
nitrogenous base
an organic base that contains nitrogen, such as a 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
deoxyribose
a five-carbon sugar that is a component of DNA nucleotides
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
