There are two main types of nuclear division : mitosis, which results in daughter cells identical to their parents ; and meiosis ( reduction division ), which produces daughter cells which have half the number of chromosomes of their parent cells, and in which the genetic material has been recombined
核分裂有兩種主要的類型:一種為有絲分裂,即子代細胞與親本相同,另一種為減數分裂,其產生的子細胞所含的染色體數為親本染色體數的一半,基因在分裂過程中發生了重組。The karyotype of nelumbo nucifera during meiosis zygotene was established in this study, which would help the studies of meiosis and molecular cytogenetics in lotus
摘要本研究建立了中國蓮偶線期染色體的核型,為研究蓮的減數分裂過程及分子細胞遺傳學研究提供基礎。Many of the heaviest nuclei can be induced to break up into two fragments of intermediate size, a process called nuclear fission.
許多最重要的原子核能被誘發分裂為兩塊大小適中的碎片,這一過程稱為核裂變。However, kit protein doesn " t exist in oogenesis after birth. there are also c - myc positive protein granules in the spermatomeres from metaphase i to telophase ii, in the spermatozoa and in the secretory cells of the spermatheca. c - myc protein expresses not in the normal follicles, but in the follicular cells of the apoptotic ones
Myc在處于減數分裂的中期至末期的精母細胞的細胞質或細胞核內呈陽性表達,在減數分裂后形成的精細胞和受精囊囊壁的上皮細胞的細胞質內也有陽性表達:但在出生后的卵子正常發生過程中無陽性表達,然而在凋亡卵泡的濾泡細胞的細胞質內有陽性表達。Main content in simulation is the spatio - temporal evolution of the set of descriptive variables characterizing tectonic mineralization state under coupling of various processes as following : ( 1 ) variables related to forming and property of ore - forming fluid, such as dissolution rate of minerals ( include metal minerals ) in rock, concentration and saturation of aqueous species in fluid, temperature, pressure, and ionic strength etc. ; ( 2 ) variables related to structural deformation and fluid flow, such as stress, deformation rate, fracture network, porosity, fracture permeability ; ( 3 ) variables related to precipitation and mineralization, such as nucleation rate of gangue and metal minerals, accumulation precipitation of various minerals, etc. ; ( 4 ) spatio - temporal coupling relation of various variables above, such as the coupling relationship between spatio - temporal evolution of fracture permeability and flow and focus of fluid and ore - forming
模擬的主要內容是在各種過程耦合作用下,以下描述構造成礦體系的主要變量的時空演化:與成礦流體的形成和性質有關的變量,如地層中礦物(包括成礦物質)的溶解速率、流體中各組分的濃度與飽和度、流體溫度、壓力、離子強度等;與構造變形和流體運移有關的各變量,如應力與變形速率、巖石孔隙度、構造(斷裂)滲透率等;與沉澱成礦有關的變量,如礦物(金屬礦物和脈石礦物)的成核速率、各礦物的沉澱量等;上述各有關變量間的時空耦合關系,如斷裂滲透率時空演化與流體流動、匯聚和成礦的耦合關系等。In addition to splitting the nucleus into two halves, the process releases two or more neutrons and a large amount of energy in the form of heat. the released neutrons in turn hit more uranium nuclei and release more neutrons to produce a chain reaction
核裂變過程除了把原子核分裂成兩份外,亦會釋放大量的熱能及同時放出兩個或以上中子,以撞擊更多鈾原子核,再釋放更多中子,產生鏈式裂變反應。Cortical granule ( cg ) is an unique type organelle of mammalian oocyte. during the maturation of oocyte, cgs shows a specific change in distribution. the generally accepted indicator of final cytoplasmic maturation is the line underneath oocyte membrane constituted by cgs
卵母細胞在成熟和受精過程中,細胞骨架發生一系列明顯的變化,微管是一種重要的細胞骨架成分,對于哺乳動物卵母細胞減數分裂的完成、精子的運動、雌雄原核的結合是必不可少的。In the course of present investigation in interspecific hybrid of tritical crops, cytomixis mas observed at microspore stage, the present investigation deals with detailed analysis of this phenomenon at different conditions
作者在麥類遠緣雜種的減數分裂過程中發現,在減數分裂的前期和小孢子時期均存在核穿壁的現象,並對各種狀態下的穿壁現象進行了詳細的觀察研究。L were studied. during the meiotic process of megasporocyte, the ribosome population diminished greatly in prophase i and restored in metaphase i ; plastids and mitochondria turned unclear dedifferentiation in prophase i and recovered their normal structures redifferentiation in metaphase i. all these proved that cytoplasmic reorganization took place during the megasporogenesis of
發現了小麥大孢子母細胞減數分裂過程中,核糖體密度在前期顯著降低,到中期才完全恢復質體和線粒體也出現了脫分化和再分化。從而證明了小麥的大孢子形成過程中也存在著細胞質改組現象。In this process the nucleus breaks up into two intermediate-sized nuclei.
在這種過程中,那個原子核分裂成兩個中等大小的核。分享友人
