English

Subject field(s)
  • Molecular Biology
DEF

A smaller nucleus located close to and lying partly within a depression on the oral side of the macronucleus.

CONT

A micronucleus (MN) is formed during the metaphase/anaphase transition of mitosis (cell division). It may arise from a whole lagging chromosome (aneugenic event leading to chromosome loss) or an acentric chromosome fragment detaching from a chromosome after breakage (clastogenic event) which do not integrate in the daughter nuclei.

French

Domaine(s)
  • Biologie moléculaire
DEF

Petit noyau, présent en plus du noyau principal des cellules et séparé de celui-ci, produit pendant la télophase de la mitose (méiose) par des chromosomes ou des fragments de chromosomes retardataires.

Spanish

Campo(s) temático(s)
  • Biología molecular
DEF

Núcleo distinto y menor que el núcleo principal de una misma célula.

OBS

Normalmente se forma en telofases anómalas, tanto meióticas como mitóticas, donde los cromosomas individuales o sus fragmentos no alcanzan el polo del huso acromático.

DEF

Ensayo in vivo a corto plazo destinado a descubrir las lesiones cromosómicas o del aparato mitótico inducidas por sustancias químicas.

OBS

Este ensayo de basa en un aumento del número de micronúcleos en los eritrocitos policromáticos de los animales tratados respecto de los animales testigo.
