Molecular biology

Maturase

Biology; Biochemistry

A nuclease involved in RNA processing; it is formed by translation of a fungal mitochondrial mRNA that is produced after a first intron is excised leaving an mRNA in which the open reading frame ...

One of two or more kinds of polypeptide chain of a heteromultimeric protein, distinguished by molecular mass, e.g. one of the larger polypeptide chains that, when combined with another heavy chain ...

Exon scanning

Biology; Biochemistry

A procedure for approximating sites of alternate splicing. In the PCR amplification of cDNA, a single primer matched to a sequence near one end, 3Â or 5Â, of the coding sequence, is paired with ...

Selfish gene

Biology; Biochemistry

A gene which confers a selective advantage upon its own propagation, but not on the survival of the individual. A classic example is Segregation Distorter in D. melanogaster: in heterozygous flies, ...

Semi-discontinuous

Biology; Biochemistry

Descriptive of the replication of DNA in which the parent strand that is exposed from its 3'-end towards its 5'-end is used as a template for continuous synthesis of a new strand, but the parent ...

Abu shunt

Biology; Biochemistry

An alternative pathway in bacteria and higher plants for entry of glutamate into the tricarboxylic acid cycle: glutamate→γ-aminobutyrate (Abu) →succinic acid semialdehyde → succinate.

Near infrared (NIR) spectroscopy

Biology; Biochemistry

In biology and medicine, a non-invasive technique for monitoring physiological parameters such as blood flow, cell volume and oxygenation level of redox molecules. NIR radiation penetrates tissues up ...
