concatenate

Biology; Biochemistry

A structure formed by two or more interlinked closed circular (cc)DNAs; formation occurs between the rapid replication of a ccDNA and the slow nicking of one of the ccDNAs to release it from the ...

catenane

Biology; Biochemistry

A structure formed by two or more interlinked closed circular (cc)DNAs; formation occurs between the rapid replication of a ccDNA and the slow nicking of one of the ccDNAs to release it from the ...

transgenic

Biology; Biochemistry

Descriptive of an animal that has developed in a surrogate mother from a fertilized ovum that had been injected with a recombinant DNA gene; contrasted with congenic, meaning of the same genetic ...

one-gene one-enzyme hypothesis

The proposal that arose from genetic studies on the effects on amino acid metabolism of mutations in Neurospora, that there is a one-to-one correspondence between enzymes and the genes that encode ...

exotoxin

Biology; Biochemistry

A disease-causing agent that is produced and secreted by a pathogen; contrasted with an endotoxin, which is an intrinsic component of the pathogen, e.g. the lipopolysaccharide of Gram-negative ...

quenching

Biology; Biochemistry

In fluorescence spectroscopy, a decrease in emission due to a variety of causes that dissipate energy of the excited state, e.g. transfer of energy to a non-fluorescent molecule such as molecular ...

mutarotation

Biology; Biochemistry

The change in optical rotation that accompanies the approach to equilibrium of the two anomers of a sugar from a solution of one anomer alone; also the conversion of one anomer of a sugar into the ...
