Molecular biology

A mechanism for repair of DNA by reduction of thymine dimers by DNA photolyase; contrasted with dark repair, an ATP-dependent process that involves excision of the dimers, resynthesis of the sequence ...

Zipper interaction

Biology; Biochemistry

The sequence of events by which an immunoglobulin G-coated lymphocyte draws the macrophage plasma membrane around it. Fc receptors on the membrane surface attach the immunoglobulin G markers and ...

Zoo blotting

Biology; Biochemistry

A technique to assess the degree to which a DNA sequence, usually a coding sequence, is conserved in evolution; a test for hybridization of a probe complementary to the sequence in one species ...

Allele-specific PCR (ASPCR)

Biology; Biochemistry

The adaptation of a PCR primer to selectivity for only one variant sequence. The 3'-end of the primer is designed to be complementary to only one allelic sequence, so the appearance of a PCR fragment ...

Buoyancy factor

Biology; Biochemistry

In analytical ultracentrifugation, one of the factors that determine a macromolecule's rate of sedimentation; (1-ur), where u is the partial specific volume of the macromolecule (expressed as ml/g) ...

Immunoaffinity chromatography

Biology; Biochemistry

A variant of affinity chromatography in which an antibody coupled to the stationary phase adsorbs an antigen which is subsequently eluted at a different pH or a higher salt concentration. Specific ...

Hierarchical condensation

Biology; Biochemistry

The hypothesis that, during the folding of a protein in solution, some regions are much more likely to adopt a secondary structure and that, once formed, these interact to direct the subsequent ...
