In this study, the stem segments of new shoot with axillary buds of well - growth tetraploid black locust trees were used as explants. the effects of different basic mediums, different hormone kinds and their concentrations ratios, different sucrose concentrations on calli induction, buds differentiation and rooting in the process of establishment of high frequency regeneration system of tetraploid black locust were studied. on the base of high frequency regeneration system, the effects of various factors on transformation efficiency of badh mediated by agrobacterium tumefaciens were discussed in the light of gus histochemical assays
本實驗首先以生長良好的四倍體刺槐優株上當年生新梢的帶腋芽莖段為外植體,研究了在四倍體刺槐高頻再生體系的建立過程中不同基本培養基、不同激素濃度及其配比、不同蔗糖濃度對愈傷組織的誘導、芽的分化及生根的影響;然後在得到高頻再生體系的基礎上,通過農桿菌介導法轉化甜菜堿醛脫氫酶( badh )基因,以gus染色組織分析為依據探討了影響轉化效率的各種因素,建立了高效、可重復的基因轉化體系,為四倍體刺槐目的基因的導入打下了基礎。During diakinesis the sister chromatids of homologous pairs of chromosomes complete their separation, and the chromosomes coil tightly, shortening and thickening
在終變期配對的同源染色體中的姐妹染色單體完成分離,染色體變成緊密凝集的狀態,縮至最小長度。Bivalent describing any pair of homologous chromosomes when they pair up during meiosis
二價染色體:在減數分裂中配對時的任意一對同源染色體。When synapsis is complete the paired chromosomes are referred to as bivalents.
當聯會完成的時候,那配成對的染色體叫做二價體。Pachytene in meiosis, the stage in mid - prophase that is characterized by the contraction of paired homologous chromosomes
粗線期:減數第一次分裂前中期中的一個階段,以配對同源染色體濃縮為特徵。Synapsis ( pairing ) the association of homologous chromosomes during the prophase stage of meiosis that leads to the production of a haploid number of bivalents
聯會(配對) :能產生單倍二價體的減數分裂前期,同源染色體的聯合現象。This usually takes the form of drawings or photographs of the individual chromosomes, often arranged in homologous pairs in numerical sequence
通常採用對單個染色體描繪和拍照的形式將其配對排列。It is due to the lack of homologous pairs of chromosomes, so chromosomes cannot pair in meiosis, and the resulting gametes may have extra or missing chromosomes
這歸因於染色體同系對的缺乏,以至於在減數分裂中染色體不能配對,導致配子有可能有額外或缺失染色體。The scheme embraces four projects, namely ( 1 ) to build up sluices at anqiu bridge and nanzhou bridge ( and the one at anqiu bridge is the first choice ) so that pollutants can be from entering the lake ; 2 ) as a necessary accessory for the above project, to supplement water capacity from changdang lake as a strategic water source into the protection program, and culvert - pipe plan is recommended from two other alternatives through systematic analysis ; 3 ) to carry out comprehensive realignment for some reed regions which are located at the entrances of the lake, and to develop a wetland ecosystem mainly with some reeds ; and 4 ) to set up a green protection belt right round the lake, including planting reeds at lakebeach, building forest belt, developing bases of green foodstuff and disposing sludges in the lake base

X染色體有許多在Y染色體上不能配對的基因。Females have two x chromosomes while males have one x and one y. when chromosomes pair, the mismatched y determines male gender
女性有二x染色體當男性有一x並且一y 。當染色體配對,被配錯的y確定男性性別。The objective of this study was whether the reconstituted embryo with the second polar body ( pb2 ) can develop. firstly, female mouse was superovulated with pmsg + hcg and keep in the same cage with male mouse, the pronuclear embryo was obtained at the different time after hcg injection with different motheds to investigate the existing time of pronuclear embryo. then pronuclear embryo was cultured with three different mediums to select the best to culture in vitro
母鼠在注射hcg后與公鼠同籠交配,並在注射hcg后不同時間(從18h到26h ) 、不同方法(體內法和體外法)獲取胚胎,研究獲取原核胚的最佳時間;在此基礎上獲得具有第二極體原核胚,然後對原核胚進行顯微操作,去除雌原核並注入第二極體,探討第二極體內遺傳物質支持胚胎發育的潛力;同時利用dna特異性染料h33342對原核胚進行染色,顯示並比較原核和第二極體內的dna遺傳物質。For the gill tissue, the best method is to dip the tissue in ringers solution for 10 minutes, then 50 minutes in 0. 04 % colchicines solution, 30 minutes in 0. 075m potassium chloride solution, fixation by carnoy ' s ; for the embryo, it is better to use 0. 02 % colchicines for 2. 5 hours and potassium chloride for 20 minutes
研究結果表明,針對鰓絲組織,取材后,使用ringers液或消毒海水中漂洗10分鐘;海水配0 . 04的秋水仙素處理50分鐘; 0 . 075m氯化鉀低滲30分鐘;正常固定滴片制備的染色體形態、分散良好。The thesis expound the method of using color comparison, color collocation, color tonality modification, color mixing, color balance, color proportion, color rhythm, color echo, and color ' s psychological effect to design the characters ' finery, prop and scene ; suggest the story ' s background ; reinforce the story ' s atmosphere ; grasp story ' s rhythm ; represent characters ' kidney and kidney ' s change ; and at last sublime the story ' s theme
闡述如何運用色彩的對比,搭配,變調,混合;色彩的平衡,比例,節奏,重點,呼應;以及色彩的視覺心理作用,來設計人物的服飾造型,道具和場景;暗示動畫中的故事背景;渲染故事情節;把握故事節奏;體現故事中人物的不同性格和性格的發展變化;最後升華故事的主題意義。In consideration of the defects of conventional ga, an improved ga has been investigated in this paper. the evolution speed and quality of the population are directly influenced by the change of the number of chromosomes in ga and by whether the paternal excellent information is passed to the offspring as much as it can. in regard to the questions existing in ga, an algorithm with dynamic population scale is provided in this paper
在對模擬電荷配置的程序化實現方面,本文採用智能優化方法? ?遺傳演算法( ga ) ,不過本文針對傳統ga - csm中遺傳演算法的定種群規模遺傳使得父本染色體的多樣性受到限制及同代非同父本進行繁殖、交叉、突變的遺傳方法可能收斂于局部極小值而得不到全局最優解的問題,對其加以改進,提出了一種新方法? ?變種群規模的遺傳演算法。The x - chromosome has many genes for which there are no paired genes on the y - chromosome
