comparative anchor tagged site (CATS)
Biology; Biochemistry
An extended DNA sequence that is sufficiently conserved across a spectrum of species, e.g. all mammals or mouse and human, so as to serve as a marker for comparative genome mapping and assist the ...
mass spectrometry
Biology; Biochemistry
A technique for separation of a stream of large ions accelerated in a magnetic field. The resistance to deflection of the ion from its path is a measure of the momentum of the ion, and hence of its ...
lipid bilayer (bimolecular sheet)
Biology; Biochemistry
A synthetic or natural membrane in which amphipathic lipids are arranged in two layers with their non-polar chains directed inwards, towards each other, and their polar groups directed outwards, ...
unit membrane Danielli-Davson model
Biology; Biochemistry
A model for the structure of biological membranes; a variation of the Danielli-Davson model in which the membrane is composed of plaques of bilayer (the unit membrane); the outer leaflet turns over ...
difference Patterson map
Biology; Biochemistry
An interim stage in the solution of a molecular structure from X-ray crystallographic data. Using only the intensities due to heavy atom reflections obtained by subtraction of the reflections of the ...
molten globule intermediate
Biology; Biochemistry
A stable intermediate between the denatured and native states of a protein which is characterized by a high content of secondary structure but poorly defined tertiary structure, hydrophobic residues ...
kinetic partitioning
Biology; Biochemistry
The hypothesis that in folding of a newly synthesized or renaturing biopolymer, a protein or RNA quickly collapses into condensed structures characterized by a high degree of secondary structure. One ...
