MOTHER CELL [11 records]

Record 1 2016-11-09

English

Subject field(s)
  • Plant Biology
DEF

The microsporocyte of a seed plant.

OBS

pollen mother cell : term extracted from the “Glossaire de l'agriculture” and reproduced with permission of the Organisation for Economic Co-operation and Development.

French

Domaine(s)
  • Biologie végétale
CONT

[...] dans les anthères très jeunes, chaque cellule sporogène est à l'origine de cellules mères du pollen par plusieurs mitoses successives, chacune de ces cellules diploïdes subissant ensuite la méiose qui conduit aux microspores haploïdes.

OBS

Record 4 2012-08-03

English

Subject field(s)
  • Genetics
DEF

The inheritance of traits controlled by genes located on the DNA of cytoplasmic organelles (in humans, mitochondria).

OBS

Being transmitted in the mitochondria of the ooplasm, the extrachromosomal genes are inherited entirely from the mother. It is non-mendelian. The many mitochondria of a cell may not be genetically identical nor are they evenly distributed to daughter cells in cell division.

French

Domaine(s)
  • Génétique
DEF

Mode de transmission de caractères héréditaires par l'intermédiaire de particules cytoplasmiques dotées d'information génétique et capables de réplication autonome.

Spanish

Campo(s) temático(s)
  • Genética
DEF

Transmisión hereditaria controlada por genes citoplásmicos.

DEF

A cell that divides to form the pair of crescent-shaped epidermal cells immediately surrounding the stomatal pore and forming the stoma.

CONT

A second unequal division gave rise to the guard mother cell(GMC), the smaller of the two derivatives.

French

Record 7 2006-08-18

English

Subject field(s)
  • Embryology
CONT

Somatic Cell Nuclear Transfer(SCNT) involves transferring the nucleus of an adult somatic cell into an enucleated egg cell. The cell is then cultured until it divides a number of times to form a blastocyst or early embryo. At this stage, the embryonic stem cells within the blastocyst may be removed. Alternatively, the embryo may be implanted into a surrogate mother and left to develop normally.

French

Domaine(s)
  • Embryologie
CONT

[La technique de clonage], avec laquelle la brebis «Dolly» a été obtenue, consiste en le transfert et en la fusion d'une cellule différenciée (et son noyau), une cellule somatique adulte par exemple, dans un ovule énucléé.

Record 8 2005-01-11

English

Subject field(s)
  • Medication
CONT

Recent media reports have painted a relentlessly gloomy picture of the status of AIDS drug development. Yet much useful information on treatment emerged at the 10th International Conference on AIDS in Yokohama, Japan(August 7-12, 1994). Encouraging treatment developments presented in Yokohama include the following : Recombinant human growth hormone therapy significantly increases weight gain as represented by fat-free lean body mass among people with AIDS-related wasting. AZT treatment dramatically reduces the rate of HIV transmission from mother to infant. Acyclovir co-treatment with anti-HIV therapy significantly increases survival time among people with AIDS. Oral ganciclovir appears to be an effective primary prophylaxis for cytomegalovirus disease. The protease inhibitor drug saquinavir reduces viral load and increases CD4 cell counts significantly more when used in a triple combination with AZT and ddC compared to 2 double combinations(AZT plus ddC or saquinavir plus AZT). Quantitative polymerase chain reaction(PCR) and branched chain DNA(bDNA) testing for measuring HIV load is expected to become a major new tool to help guide individual treatment decisions and to evaluate anti-HIV therapies in clinical studies.

French

Domaine(s)
  • Médicaments

Chaque étape du cycle de réplication du virus est la cible potentielle d'un médicament contre le sida.

CONT

[...] l'azidothymidine ou AZT constitue sans aucun doute le plus connu des médicaments du sida.
