• depends
  • We show that the Piwi Argonaute PRG-1 and its genomically encoded piRNA cofactors initiate RNAe, while maintenance depends on chromatin factors and the WAGO Argonaute pathway. (pubmedcentralcanada.ca)
  • The integrity of chromosome ends, or telomeres, depends on myriad processes that must balance the need to compact and protect the telomeric, G-rich DNA from detection as a double-stranded DNA break, and yet still permit access to enzymes that process, replicate and maintain a sufficient reserve of telomeric DNA.

  • regulation
  • Cytotype regulation of transposable P elements in the germ line of Drosophila melanogaster is associated with maternal transmission of P elements inserted at the left telomere of the X chromosome. (genetics.org)

  • sequence
  • Phylogenetic analysis did not identify a species containing an ITS2 sequence more similar to either of the B chromosome sequences than the B. dichromosomatica A chromosome sequences. (jove.com)
  • A consensus definition of the concept of epigenetic trait as "stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence" was formulated at a Cold Spring Harbor meeting in 2008, although alternate definitions that include non-heritable traits are still being used.

  • single
  • A single molecule of DNA within a chromosome may be as long as 8.5 centimeters (3.3 inches). (encyclopedia.com)
  • Causal elements of this condition, referred to as intragenomic conflict, range from single loci to whole chromosomes, and their 'drive' phenotypes often involve disruption of nuclear processes involved in gametogenesis or early embryogenesis 1 , 2 , 3 , 4 . (pubmedcentralcanada.ca)
  • cell division
  • However, others use the concept in a narrower sense, to refer to the individualized portions of chromatin during cell division, visible under light microscopy due to high condensation. (wikipedia.org)
  • several
  • The impaired regulatory ability of TP5 persists for at least several generations after TP5 X chromosomes extracted from a long-term mutant Su(var)205 stock are made homozygous in the absence of the Su(var)205 mutation. (genetics.org)
