流式細胞術在精子染色質結構分析中的應用Chromatin is the material that makes up chromosomes ; it consists of dna complexed with proteins
由dna和蛋白質組成的染色質,是構成染色體的原料。The ultrastructure of the merozoites of eimeria tenellawas observed and discribed. the pellicle consist of two layer membranes, the outer membrane was a continous covering enclosing the whole merozoites, while the inner pellicular complex is interrupted at the anterior and the micropore, and thicken to form the polar ring and micropore. there are 24 microtubules under the pellicle of the merozoite which originated from the polar ring, all of them are connected with the polar ring, and extend alongside the inner pellicular complex to the middle of the merozoite. the head of the merozoite consists of a conoid, an apical vesicule and polar ring. the conoid is a hollow truncated cone. the conoid and spical vesicule can stretch and contract. there are three or more rhoptry and a lot of micronemes. the nucleus has nucleolus. and two layer membranes
利用透射電鏡對柔嫩艾美耳球蟲裂殖子的超微結構進行了觀察描述.柔嫩艾美耳球蟲裂殖子的表膜由外膜和內膜復合體兩層組成,外膜連續,內膜復合體在頭部斷開形成極環,在其它部位斷開形成微孔;裂殖子的膜下微管24根,起始於極環,向後延伸至細胞核處;裂殖子的頭部由頂泡、錐體和極環組成,錐體和頂泡可以伸縮;柔嫩艾美耳球蟲裂殖子棒狀體3個以上,微線數量很多,二者都由電子緻密的結構組成;細胞核位於裂殖子的中後部,外被雙層膜,有電子緻密的核仁和染色質The origin of such large amounts of constitutive heterochromatin and their role in karyotype evolution and speciation remain a mystery.
如此大量的結構異染色質的來源及其在染色體組型進化和物種形成中的任務仍是一個謎。At low concentration of zn, the changes in ultrastructure were nuclei deformation, chloroplast swelling and disorder of thylakoid arrangement ; serious damages in ultrastructure caused by greater zn stress were indicated by scattered nucleoli, condensed chromatin, almost empty nuclei with nuclear membrane disrupted and nucleoplasm flowing into cytoplasm, swollen and partly dissolved cristae of mitochondria, disrupted and collapsed chloroplast envelopes, and some dissolved thylakoids that flew into cytoplasm
超微結構的變化也呈現加重趨勢,低濃度處理的變化為細胞核變形、葉綠體膨脹、類囊體排列紊亂;嚴重的超微結構的損傷是核仁散開、染色質凝集,細胞核幾乎成為空核和核膜破裂,核質散出;線粒體脊突膨脹和部分溶解;葉綠體膜斷裂、消失和部分類囊體溶解和散到細胞質中。That which shows the "normal" condensation pattern is called euchromatin.
那些表現「正常的」濃縮格式的部分叫做常染色質。Zones of loosely arranged euchromatin are located mainly in the center of the nucleus.
疏鬆的染色質區帶主要位於細胞核的中心部。Their nuclei are pale and vesicular, containing mainly unstained euchromatin
細胞核染色蒼白呈空泡狀,應為主要含有的是不著色的常染色質。Cells take diverse shapes. these are epithelial cords of block - like cells. as always, nucleoli and nuclear heterochromatin stain darkly with hematoxylin
不同形態的細胞。這些是立方細胞排列成的上皮索狀結構。總之,核仁與細胞核中的異染色質被蘇木精染成深色。Heterochromatic areas tend to stain intensely during interphase, sometimes forming condensed masses called chromocentres.
異染色質部分在間期有染色很濃的傾向,有時形成濃縮的塊狀,這些塊狀叫做染色中心。Chromosome material with exhibits of such behaviour is called heterochromatin.
表現這種現象的染色體物質叫做異染色質。Heterochromatin has shown to be composed largely of short repeated polynucleotide sequences.
異染色質大部分是由短而重復的多核苷酸序列所組成的。Epigenetic modification of the genome ensures proper gene activation during development and involves : genome methylation changes ; the assembly of histon and histone variants into nucleosomes and remodeling of other chromatin - associated proteins such as linker histones, polycomb group, nuclear scaffold protein, and transcription factors
這些染色質的再程序化包括dna的甲基化和核小體組蛋白的乙酰化等。組蛋白乙酰化在染色質結構調節、 dna復制、基因轉錄、細胞分化及癌細胞發育都有研究,但在克隆動物中卻是一個有待深入探索的領域。Abstract : the nucleosome, the structural unit of chromatin, is known to play a central role in regulating gene transcription from promoters
摘要:核小體作為染色質的結構單位,在基因啟動子區域調節基因轉錄中具有重要的作用。Clones are lost from the earliest developmental stages and throughout pregnancy. now more and more studies support the evidence on the failure of cloning : chromatin inappropriate epigenetic reprogramming, and then result in abnormal genes expression
大量的研究表明,克隆動物在核移植后其染色質的再程序化表現異常,使細胞不能成功地通過調節轉錄活性而有效地控制其發育分化。Under mirror obviously ; the cell apoptosis divides into the early stage, the intermediate stage, stage of formation of apoptosis body and the later period stage ( three issuses of four stges ), its ultrastructure is mainly observed the cellular form, the cytoblastema, the nucleus, the chromatin change, the special sign of cell apoptosis - apoptosis body
鏡下可見:細胞凋亡分為早期階段、中期階段、凋亡小體形成階段和晚期階段( 3期4階段) ,其超徽結構主要可見到細胞形態、胞漿、胞核、染色質的變化,及細胞凋亡的特異性標志凋亡小體。分享友人
