Hetairokaryote

Biology; Biochemistry

The endosymbiotic product of a eukaryotic cell dwelling within another eukaryotic cell; as contrasted with the mitochondrion and chloroplast, which are believed to be endosymbiotic products of a ...

Short-column method

Biology; Biochemistry

An analytical ultracentrifugation technique for measurement of the molecular mass of a protein; requires relatively brief periods of time because it uses very short columns of liquids since the ...

A conserved sequence in yeast mitochondrial unassigned reading frames, about 1kb long, that is part of an intron the 5'-end of which has the consensus sequence coding for the LAGLI pentapeptide and ...

Hill coefficient

Biology; Biochemistry

A measure of co-operativity, i.e. the number h in the equation (HbO 2 )/(Hb)=k(pO 2 ) h that empirically describes the dependence of haemoglobin (Hb) oxygenation on the partial pressure of ...

Biuret reaction

Biology; Biochemistry

A colour reaction for the quantification of protein in solution. By analogy with the compound biuret (H 2 N-CO-NH-CO-NH 2 ), the peptide backbone of proteins reacts with alkaline copper solutions to ...

Shuttle vector

Biology; Biochemistry

A plasmid that has both bacterial and eukaryotic origins of replication and so can propagate in either kind of cell; useful as a form of recombinant DNA for growth in a bacterium and subsequent ...

Proto-

Biology; Biochemistry

Borrowing from historical linguistics, a prefix that denotes the simplest possible precursor of two or more organisms, inferred from phylogenetic trees reconstructed from polynucleotide sequences, ...
