Complementary base sequences

Because the protruding termini of coRI fragments have complementary base sequences, they can form base pairs with one another. 

Predicting the Complementary Base Sequence in Double-Stranded DNA... 

RNA exists as a single strand, whereas DNA exists as a double-stranded helical molecule. However, given the proper complementary base sequence with opposite polarity, the single strand of RNA—as demonstrated in Figure 35-7—is capable of folding back on itself like a hairpin and thus acquiring double-stranded characteristics. 

Probe Single-stranded DNA or RNA molecules of specific base sequence, labeled either radioactively or immunologically, that are used to detect the complementary base sequence by hybridization. 

DNA tests rely on two basics facts, 1) the distance a molecule of DMA moves in a thin slap or small column of gelatin-like material when an electric current is passed through it depends on the length of the piece of DNA, a process called electrophoresis and 2) single strands of DNA will bind to each other if they have complementary base sequences An A will pair with a T, a T with an A, a G with a C, and a C with a G. 

Nucleic acid. complementary base sequence, histones, nucleic acid pol3rmerase, nucleic acid binding protein. 

DNA usually adopts the double-chain twisted ladder structure (the double helix) shown in Figure 16-18 with complementary base sequences allowing hydrogen bonding between the two chains, as in... 

Complementary base sequence. For a given sequence of nucleic acids, the nucleic acids that are related to them by the rules of base pairing. 

Some typical biological interactions, frequently used in affinity chromatography are enzyme to substrate analogue, inhibitor, or cofactor antibody to antigen, virus, or cell lectin to polysaccharide, glycoprotein, cell surface receptor, or cell nucleic acid to complementary base sequence, histones, or nucleic acid polymerase hormone or vitamin to receptor, or carrier protein glutathione to glutathione-S-transferase (GST) or GST fusion proteins and metal ions to poly (His) fusion proteins, or native proteins with histidine, cysteine and/or tryptophan residues on their surfaces. 

A cruciform. A nucleic acid molecule is shown in a cruciform structure. Two strands with complementary base sequence are shown with the backbones highlighted in purple, the individual bases are the short lines perpendicular to the backbones. Base pairing occurs wherever a base is shown joined to its partner. Note that both interstrand and intrastrand base pairing occur.
