Chromatin
Definition:
(n.) Tissue which is capable of being stained by dyes.

(16) Poly (ADP-ribose) polymerase, a nuclear protein-modifying enzyme, binds to the internucleosomal linker region of chromatin, although it modifies certain core nucleosomal histones in addition to histone H1.
(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.
(3) The data obtained in the study of the dependence of sensitivity of enzyme immunoassay (EIA) on chromo- and fluorogenic substrates used in this assay are presented.
(4) Our results demonstrate for the first time that the chromo domain is important for the function of Pc and that it is absolutely required for binding of Pc protein to chromatin.
(5) The separation of amino acids has been achieved on a short column of Chromo-Beads C2 resin, with a lithium gradient-elution system.
(6) The data provide an example of broken chromo-some healing, and underscore the importance of the telomeric repeat structure for recognition of functional telomeric DNA in vivo.
(7) The chromium(III) complex of ATP, an MgATP complex analogue, inactivates (Na+ + K+)-ATPase by forming a stable chromo-phosphointermediate.
(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.
(11) A family of sequences with a low percentage of guanosine plus cytidine was highly concentrated in a particular region within the chromo-center.
(12) However, the failure of chromo somes to become properly aligned onto the metaphase plate indicated an impairment in normal prometaphase movement.
