Record 1 2013-11-15

English

Subject field(s)
  • Genetics
DEF

The smallest unit (corresponding to a single DNA nucleotide) which is exchangeable but not divisible by intragenic recombination between homologous linkage structures (chromosomes).

French

Domaine(s)
  • Génétique
DEF

Le plus petit élément génétique qui puisse être échangé entre des chromosomes ou des molécules nues d’acide désoxyribonucléique homologues par recombinaison génétique sans pouvoir subir de fragmentation. Il correspond à un seul nucléotide de la chaîne polymérique.

English

Subject field(s)
  • Cytology
  • Biotechnology
CONT

[Apoptosis is a] naturally occurring, non-pathologic form of cell death distinct from necrosis, characterized by condensation of the nucleus and cytoplasm, extensive bleeding, and breaking up of the cell into a number of membrane-bound fragments (apoptotic bodies), which are then either phagocytosed by neighboring cells or shed into a lumen.

French

Domaine(s)
  • Cytologie
  • Biotechnologie
CONT

En réponse à un signal d’activation incomplet, la cellule s’autodétruit en quelques heures. La fragmentation de ses chromosomes s’accompagne d’une condensation périphérique du noyau. La cellule se scinde en petits ballons, sans lésion de la membrane ni des constituants intracellulaires. Ces ballons sont intégrés par les cellules voisines. Quand le signal d’activation est complet, la cellule se multiplie et acquiert des propriétés nouvelles.

Record 3 1986-12-15

English

Subject field(s)
  • Cytology
CONT

An alternative approach to the problem of establishing gene linkage in somatic cells is to induce random chromosome fragmentation by irradiating cells before fusing them with a recipient cell, and then following in the hybrid the retention of two genes mapped to the same chromosome.
