Chromatin


Definition:

  • (17) Micrococcal nuclease-digested testis and erythrocyte chromatin was separated into soluble and insoluble fractions.
  • (18) Topoisomer heterogeneity for plasmid chromatin in vivo may be due to heterogeneity in the number of nucleosomes on each plasmid, which could reflect either the nature of the assembly process or the dynamics of nucleosomes within the cell.
  • (19) Such a heterogeneity in DNA content in the diploid part of HPR cell population could apparently suggest some differences in the nuclear chromatin arrangement to be always higher in spring before the frog spawning, and it seems to be characteristic of this type of cells.
  • (20) These observations demonstrate that brain cells synthesize a NGF mRNA in primary culture and that the butyrate moiety of db-cAMP enhances NGF gene expression in these cells, probably by a modification of chromatin structure in and around the NGF gene.

Chromo


Definition:

  • (n.) A chromolithograph.

Example Sentences:

  • (1) In the immunocytochemical step, the avidin-biotin-peroxidase complex coupled to a new chromogen, Chromo-red, produced a bright red reaction product in neurons containing luteinizing hormone-releasing hormone-like material.
  • (2) Some of the nuclear patterns generated by the mutated forms of the fusion proteins suggest, furthermore, that the chromo domain could be involved in a packaging mechanism, essential for compacting chromosomal proteins within heterochromatin or heterochromatin-like complexes.

  • (8) 2) Chromoblastomycosis--A verrucous, slow growing nodule or plaque produced by fungi, characteristically and exclusively present as large brown spherical bodies (chromo bodies) in the dermis.
  • (9) These findings were compared with those of hysterosalpingography (HSG) or chromo-laparoscopy which were done during the same anesthesia.
  • (10) Plasticized poly(vinyl chloride) membranes that incorporate a highly lipophilic sodium-selective neutral ionophore (ETH 4120) and novel H(+)-selective chromo-ionophores, lipophilic isologs of Nile Blue, are used in the competitive binding of Na+ and H+ for a reversible, optical determination of sodium activities in buffered solutions at different selected pH values.
