Contributors in Biochemistry

Biochemistry

The average time that a population of fluorophores spends in the excited state before collapse to the ground state. The lifetime is equal to the reciprocal of the first-order rate constant for the ...

Complementary

Biology; Biochemistry

In nucleic acid chemistry, descriptive of the relationship between two polynucleotides that can combine in an antiparallel double helix; the bases of each polynucleotide are in a hydrogen-bonded ...

Immunoelectrophoresis

Biology; Biochemistry

A method for analysis of antibody or antigen mixtures. A solution of antibodies is electrophoresed in a gel, then exposed to an antigen solution placed in a trough cut into the gel parallel to the ...

Star activity

Biology; Biochemistry

A secondary nucleotide sequence specificity of an endonuclease. After the canonical specificity is established, a library of potential substrates may be created by substituting at each sequence ...

Transesterification

Biology; Biochemistry

The substitution of one alcohol for another in an ester bond, e.g. the displacement of one 3'-hydroxy group of a phosphodiester bond by the 3'-hydroxy group of another nucleotide during the ...

Globular

Biology; Biochemistry

Descriptive of the folding of a protein upon itself in several convolutions to create interactions of the side chains in many weak salt bridges, hydrogen bonds and hydrophobic bonds that result in a ...

Thick filament

Biology; Biochemistry

In muscle cells, an aggregate of myosin molecules in which the long, fibrous tails are intertwined in a superhelix that leaves the globular heads as knobs in a helical array over the surface. The ...
