EPIGENIC [4 records]

Record 1 2011-12-14

English

Subject field(s)
  • Paleontology
DEF

[Which can] be converted into a fossil.

CONT

Organisms may produce fossilizable traces on the sediment surface(epigenic structures) or within the sediment(endogenic structures).

French

Domaine(s)
  • Paléontologie

Qui peut être fossilisé.

Record 2 2011-08-31

English

Subject field(s)
  • Genetics
  • Biotechnology
CONT

Using this knowledge, an emerging use of PTGS and, in particular, RNA interference (RNAi), the initiating of PTGS by introducing small (21-25 nucleotides) double-stranded RNA (siRNA), as a tool to knock out the expression of specific genes in a variety of organisms can be observed.

OBS

Epigenic silencing of transgene and endogenous genes can occur at the transcriptional level(TGS) or at the post-transcriptional level(PTGS).

OBS

post-transcriptional silencing: Elliptical form of "post-transcriptional gene silencing." As the term "silencing" can only apply in this context to genes, the term "gene" can be removed.

Key term(s)
  • posttranscriptional gene silencing

French

Domaine(s)
  • Génétique
  • Biotechnologie
DEF

Phénomène ou mécanisme cytoplasmique de mise en sommeil des gènes qui peut être d'origine naturelle ou provoqué in vitro et qui induit une destruction sélective de l'ARNm [ARN messager] pour lequel correspondent au moins une centaine de nucléotides.

OBS

PTGS : Bien qu'issue de l'expression anglaise «Post Transcriptional Gene Silencing», cette abréviation est utilisée dans les textes français.

Spanish

Campo(s) temático(s)
  • Genética
  • Biotecnología
DEF

Degradación citoplasmática del ARNm [ácido ribonucleico mensajero] de un gen específico debido a la presencia de ARNbc [ácido ribonucleico bicatenario] complementarios a él.

Record 3 2011-07-19

English

Subject field(s)
  • Various Metal Ores
DEF

In ore petrology, applied to mineral deposits of later origin than the enclosing rocks ...

CONT

An epigenetic deposit ... is one believed to have come into being after the host rocks in which it occurs. A good igneous analogy is a dyke; an example among ore deposits is a vein.

OBS

As opposed to "syngenetic" which applies to mineral deposits formed contemporaneously with the enclosing rocks.

French

Domaine(s)
  • Minerais divers (Mines métalliques)
DEF

S'applique à des gîtes minéraux mis en place après la formation des roches encaissantes.

CONT

Il est toujours délicat de trancher entre les concrétions syngénétiques, contemporaines des sédiments dans lesquels on les rencontre, et les concrétions épigénétiques formées tardivement.

Record 4 2001-12-13

English

Subject field(s)
  • Mineralogy
  • Geochemistry
OBS

See "epitaxy" and "epigenetic."

French

Domaine(s)
  • Minéralogie
  • Géochimie
CONT

Les paragénèses métallogéniques s'expliqueraient souvent par une épitaxie épigénétique où le cristal dépôt s'installe sur le support préexistant [...] ou en est même expulsé (scheelite sur wolfram, rutile sur anatase, calcite sur aragonite).
