Biochemistry

Transforming factor

Biology; Biochemistry

In the classical experiments by Avery, MacLeod and McCarty, the name given to the agent that caused the heritable transformation of R strains of Streptococcus pneumoniae into S strains. The ...

In mass spectrometry, an N-terminal fragment of a polypeptide produced by cleavage of the bond between an α-carbon and its neighbouring α-carboxy carbon. A b-type ion is an α-N-terminal acylium ion ...

Linkage

Biology; Biochemistry

In genetics, the more-frequent-than-random occurrence of two traits together due to their proximity on the same chromosome. The likelihood of a recombination event separating the two traits decreases ...

Glycoconjugate

Biology; Biochemistry

A compound composed of an oligosaccharide linked to a protein or lipid, e.g. mucins (which are glycoproteins), globosides (which are N-acetylsphingosine conjugates of oligosaccharides), and the ...

Core protein

Biology; Biochemistry

One of the proteins to which are attached the carbohydrate chains (e.g. chondroitin sulphate, keratan sulphate) of a proteoglycan, and which with them comprise the subunits of the proteoglycan.

Electrophoresis

Biology; Biochemistry

A technique that separates charged compounds according to their mobilities in an electric field. In free zone electrophoresis the compounds are in a solution unsupported by any stabilising matrix. In ...

Mismatched PCR

Biology; Biochemistry

A method for detection of a point mutation that neither produces nor destroys a restriction site; intended especially for screening large numbers of individuals. One of the PCR primers is designed so ...
