What's the difference between achromatin and chromatin?
Achromatin
Definition:
(n.) Tissue which is not stained by fluid dyes.
Example Sentences:
(1) These changes pointed to destructive action of the preparations under consideration on chromosomes and achromatine spindle, and from the author's point of view, characterized toxic properties of sensitin.
(2) Unlike other coccidia, during the microgametogenesis in C. parvum, the nuclear substance of the daughter nuclei is not separated into osmiophilic (containing the condensed chromatin) and achromatinic parts.
Chromatin
Definition:
(n.) Tissue which is capable of being stained by dyes.
Example Sentences:
(1) Here we report that sperm from psr males fertilizes eggs, but that the paternal chromosomes are subsequently condensed into a chromatin mass before the first mitotic division of the egg and do not participate in further divisions.
(2) These studies led to the following conclusions: (a) all the prominent NHP which remain bound to DNA are also present in somewhat similar proportions in the saline-EDTA, Tris, and 0.35 M NaCl washes of nuclei; (b) a protein comigrating with actin is prominent in the first saline-EDTA wash of nuclei, but present as only a minor band in the subsequent washes and on washed chromatin; (c) the presence of nuclear matrix proteins in all the nuclear washes and cytosol indicates that these proteins are distributed throughout the cell; (d) a histone-binding protein (J2) analogous to the HMG1 protein of K. V. Shooter, G.H.
(3) The use of ethidium for chromatin cytochemistry allows to study chromatin properties in wide ranges of pH.
(4) The isoenzyme mobility diminished in both tumour chromatin extracts, and the slow migrating gamma isoenzyme exhibited sensitivity to L-cysteine inhibition.
(5) Its presence suggested an implication in the enhanced activities of RNA polymerases of E 24 chromatin.
(6) In the absence of n-butyrate, only a small percentage (approximately 4%) of the total beta A chromatin is in a soluble chromatin fraction following micrococcal nuclease digestion and centrifugation.
(7) Likewise, [3H]estradiol-receptor complexes from rabbit uterus, Squalus oviduct, or mouse testis bound minimally to Squalus testicular chromatin.
(8) Indirect end-labeling analysis of micrococcal nuclease digested chromatin reveals that nucleosomes are identically phased on the mouse mammary tumor virus long terminal repeat in normal and hyperacetylated chromatin.
(9) Since chromatin particles containing DNA the size of 125 kbp can electroelute, we conclude that the polymerizing complex is attached to a nucleoskeleton which is too large to escape.
(10) In addition our studies reveal that the binding patterns of [3H]GR isolated from mammary glands of nulliparous and lactating mice to their homologous chromatin is essentially similar.
(11) Quantitative cytophotometry and ocular filar micrometry were used to monitor T-2 toxin induced alterations in chromatin and neuronal nuclear volume in supraoptic-magnocellular neurons of rat hypo-thalami.
(12) We therefore sought to determine whether doxorubicin in the presence of NADH dehydrogenase and the transition metal ions Fe(III) or Cu(II) induces DNA base modifications in isolated human chromatin.
(13) In contrast, interchange of the histones and tightly bound non-histone protein DNA complexes from hormone-withdrawn and estrogen-stimulated chromatins during reconstitution did not affect the level of mRNAOV sequences produced.
(14) Mechanisms of investigated phenomenon, particularly their dependence on the chromatin structure, as well as the influence of ionic strength on binding the repair enzymes with DNA are discussed.
(15) The blood lymphocytes were small with scanty cytoplasm, densely condensed nuclear chromatin, and deep clefts originating in sharp angles from the nuclear surface.
(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.
