Two DNA bases that are complementary to one another (A and T, or G and C) and join in strands to form the double-helix that is characteristic of DNA.

Molecules called nucleotides, on opposite strands of the DNA double helix, that form chemical bonds with one another. These chemical bonds act like rungs in a ladder and help hold the two strands of D [..]

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine [..]

In genetics, nucleotides are called bases. A base pair (bp) is two complementary nucleotides on opposite strands of DNA. Base pairs are measured using metric units. 1 base pair = 1 base pair (bp) 1,00 [..]

A base pair is two chemical bases (A, T, C or G) bonded to one another via hydrogen bonds. You can find out more about base pairs on the Wikipedia page: http://en.wikipedia.org/wiki/Base_pair

One pair of complementary nucleotides within a duplex strand of a nucleic acid. Under Watson-Crick rules, these pairs consist of one pyrimidine and one purine: i.e., C-G, A-T (DNA) or A-U (RNA).

Two bonded nucleotide bases joined to opposite strands of the DNA

  A pair of nitrogenous bases (usually one purine and one pyrimidine) held together by hydrogen bonds in a double-stranded region of nucleic acid molecule. Commonly used interchangeably with nucleotid [..]

Two DNA bases paired up, like rungs on a ladder, which produces the double helix structure.

two complementary nucleotide bases joined together by chemical bonds. The two strands of the DNA molecule are held together in the shape of a double helix by the bonds between base pairs. The base ade [..]

Association of two complementary nucleotides in a DNA or RNA molecule stabilized by hydrogen bonding between their base components. Adenine pairs with thymine or uracil (A·T, A·U) and guanine pairs wi [..]

Pairing of purine and pyrimidine bases by Hydrogen Bonding in double-stranded DNA or RNA.

Two nitrogen-containing bases pair together between double-stranded DNA; only specific combinations of these bases (e.g., adenine with thymine; guanine with cytosine) are possible, a fact which facilitates accurate DNA replication; when quantified (e.g., 8 base pairs, or bp), this term refers to the actual number of base pairs in a sequence of nucl [..]

A unit of nucleic acid length, based on the number of paired bases (adenine and thymine, guanine and cytosine) in a DNA double helix.

Two nitrogenous (purine or pyrimidine) bases (adenine and thymine or guanine and cytosine) held together by weak hydrogen bonds. Two strands of DNA are held together in the shape of a double helix by [..]

A pair of complimentary nucleotides. In DNA, the nucleotide adenine (A) always binds with thymine (T), and guanine (G) binds with cytosine (C). In RNA, uracil (U) binds with adenine, rather than thymi [..]

A (Adenine) pairs with T (Thymine) and C (Cytosine) pairs with G (Guanine). These base pairs form the ladder of the DNA molecule.

In double-stranded nucleic acids, a "base pair" is the structure formed between two complementary nucleotides by hydrogen bonding. In DNA, adenine(A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). In RNA, adenine (A) pairs with uracil (U) and cytosine (C) pairs with guanine (G).

One of the pairs of chemical bases in the DNA double helix that carries genetic information.
