a naturally occurring or synthetic compound consisting of large molecules made up of a linked series of repeated simple monomers

(biochemistry) purine base found in DNA and RNA; pairs with thymine in DNA and with uracil in RNA

a base found in DNA and RNA and derived from pyrimidine; pairs with guanine

a purine base found in DNA and RNA; pairs with cytosine

a base found in DNA (but not in RNA) and derived from pyrimidine; pairs with adenine

(genetics) a segment of DNA that is involved in producing a polypeptide chain; it can include regions preceding and following the coding DNA as well as introns between the exons; it is considered a unit of heredity

one of the pairs of chemical bases joined by hydrogen bonds that connect the complementary strands of a DNA molecule or of an RNA molecule that has two strands; the base pairs are adenine with thymine and guanine with cytosine in DNA and adenine with uracil and guanine with cytosine in RNA

(biochemistry) any of various macromolecules composed of nucleotide chains that are vital constituents of all living cells

the organic chemistry of compounds and processes occurring in organisms; the effort to understand biology within the context of chemistry

a segment of DNA containing adjacent genes including structural genes and an operator gene and a regulatory gene

single-stranded DNA that is complementary to messenger RNA or DNA that has been synthesized from messenger RNA by reverse transcriptase

DNA that is not incorporated into the genome but is replicated together with the genome (especially in bacterial cells)

sequence of a gene's DNA that transcribes into protein structures

sequence of a eukaryotic gene's DNA that is not translated into a protein
