  • Thus, cells which exhibit larger nucleoli have usually not retained the extrachromosomal array. (wikipedia.org)
  • Cells lacking the extrachromosomal array also lack the functional gene of interest. (wikipedia.org)
  • Mosaic analysis using a ncl-1 (+) extrachromosomal array reveals that lin-31 acts in the Pn.p cells during Caenorhabditis elegans vulval development. (wikipedia.org)
  • A statistically significant decrease in MDR 1 extrachromosomal gene copy number was reproducibly detected in the irradiated cells compared with unirradiated cells passaged for the duration of the experiment in the absence of radiation treatment. (aacrjournals.org)
  • In fact, pE10 hybridizes exclusively with unfractionated DNA from leaf protoplasts, while it recognizes predominantly an extrachromosomal DNA molecule (ECD) of about 45 kb and its multiples in the case of protoplasts from cultured cells. (unipv.it)
