base pair definition

  • noun:
    • The couple of nitrogenous bases, composed of a purine linked by hydrogen bonds to a pyrimidine, that links the complementary strands of DNA or of crossbreed particles joining DNA and RNA. The beds base sets are adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.
    • In molecular biology, two nucleotides on opposite complementary DNA or RNA strands which are connected via hydrogen bonds.
    • a unit of double-stranded DNA or RNA consisting of two complementary basics on opposing strands regarding the double-stranded polynucleotide, bound together by hydrogen bonds as well as other non-covalent substance forces. The basics comprising the base sets are adenine, thymine, cytidine, and guanine. In typical DNA, the bottom adenine on one strand of DNA sets with thymine on opposing strand, and cytosine on a single strand sets with guanine regarding opposing strand. The word base pair typically includes the sugar (ribose or deoxyribose) plus the phosphate bound to every base to make a nucleotide unit. One base set might be used as a unit of length or size for DNA, plus this usage is abbreviated bp. A length of 1000 base sets is a kilobase set or kbp.
    • one of the pairs of substance bases joined up with by hydrogen bonds that link the complementary strands of a DNA molecule or of an RNA molecule with two strands; the base sets tend to be adenine with thymine and guanine with cytosine in DNA and adenine with uracil and guanine with cytosine in RNA
