Biochemistry

Nucleotide

Biology; Biochemistry

A nucleoside with one, two or three phosphate(s) esterified to one of the free hydroxy groups of the sugar moiety, usually the 3'- or 5'-hydroxy group; ribonucleotide if the sugar is D-ribose; ...

Nucleoside

Biology; Biochemistry

A purine or pyrimidine base with a sugar attached in a glycosidic linkage; ribonucleoside if the sugar is D-ribose and deoxyribonucleoside if the sugar is D-deoxyribose.

A category of polynucleotides, usually from 70 to 500 nucleotides in length. As complexes with proteins (snrps) they have several functions, among them the processing of pre-mRNA, either directly as ...

Intron

Biology; Biochemistry

From intervening sequence region; originally defined as a non-coding polynucleotide sequence that interrupts the coding sequences, the exons, of a gene. More recent evidence indicates that, in some ...

Intron editing

Biology; Biochemistry

A change in the reading of the sequence coded by DNA directed by an adjacent intron. The intron, which has a sequence complementary to part of the exon, forms a double-stranded stem structure that is ...

Electron spin resonance (ESR)

Biology; Biochemistry

Also known as electron paramagnetic resonance (EPR); a magnetic resonance technique that detects and characterises the environment of a moiety that contains an unpaired electron by the energy that is ...

Doublet

Biology; Biochemistry

A subunit of the axoneme in which 10 microtubule protofilaments are grafted longitudinally on to a whole microtubule, which itself consists of 13 protofilaments. Also, in magnetic resonance, a peak ...
