作為cyclin依賴激酶, cdc2的激酶活性在很大程度上抑制了細胞的合成代謝,使細胞的蛋白合成進入了一個相對的靜止期,而細胞主要的能量則被應用於細胞分裂時的染色體的濃縮、核膜的降解、紡錘體的形成等。The plane of cell division is, in turn, determined by the orientation of the mitotic spindle.
細胞分裂的方向又是由有絲分裂的紡錘體所確定。The tenuous state of the chromosomes during the period between cell divisions should not suggest that they are inert at this time.
在細胞分裂期間,纖細狀態的染色體並不表明此時它們是不活躍的。Growth resulting from increase in cell size without cell division
生長指由於細胞體積的增大而非細胞分裂而導致的生長At the start of cell division, fibrils appear to radiate from the centrioles, forming starlike asters
在細胞分裂開始時,從中心粒發出星狀的纖維,即星體。Prior to cell division it replicates, and the sister centrioles move to opposite ends of the cell to lie within the spindle - organizing structure, the centrosome
它在細胞分裂之前復制,其中一個中心粒移向細胞的另一端,組織紡錘體和中心體。When the cells synchronized at a late cytokinesis stage were treated with w7, the dissolving of the midbody was delayed ; furthermore, we found that the dissociation of y - tubulin from the midbody was also inhibited
W7處理同步化在胞質分裂後期的細胞,不但使中體解聚發生延遲,而且抑制了y一微管蛋白與中體的解離。3. the development of the anther wall follows the basic type. cytokinesis in the microspore mother cell is of the successive type. the arrangement of microspore in tetrad is tetrahedral. mature pollen grain is of 2 - celled type. the anther has 4 four rooms, accidentally seen six or seven rooms
花藥壁的發育為基本型,小孢子減數分裂為連續型,小孢子四分體為四面體型,成熟花粉為二細胞型。花藥多為四室,偶見六室和七室。 4Initiation of somatic cells stimulated by cytokinin, division of the initiated somatic cells and succeeding shoot meristem development are three key steps in the process
細胞分裂素誘導體細胞啟動、啟動的體細胞進行分裂和由此引發的莖分生組織發育是這一過程中的3個重要步驟。Floral organs have been successfully induced from the regenerated floral buds of ffyacinthus orienralis l. by precisely controlling exogenous hormones in the medium. under high concentration of cytokinin and auxin, the regenerated floral bud produces only tepals
以風信子花被片為外植體,通過控制培養基中細胞分裂素和生長素的濃度,可誘導花芽的再生和控制產生花器官的種類,建立起離體花器官定向控制系統。140min, chromosomes of the daughter cells are situated at metaphase of the second karyokinesis, while the daughter cells do n ' t separate
120min ,染色體處于有絲分裂末期,分裂溝形成,受精卵徑裂為二細胞。受精140min ,再徑裂為4細胞。If chromosome segments break away during nuclear division they may rejoin the chromosome the wrong way round, giving an inversion
如果在細胞核分裂的時候染色體的某些片斷斷裂,繼而在同一染色體上的某個片斷作了方向錯誤的顛倒,這種現象叫做倒位。Ceviar living cells, which undergo devision 200 times faster than normal cells, contain a great variety of activated factors that stimulate fission of both organism and cells, and regeneration of cells, improving micro circulation and supply of nutrients, reducing melanin, and thus growing vitality and skin springiness, resulting from less wrinkles and shrinking pores
魚子活細胞有旺盛的生命力,它的細胞分裂頻率比成熟細胞強200倍,內含多種活性因子,可啟動人體組織細胞的分裂和活化,刺激老化細胞更新再生,改善微循環,淡化黑色素,其高分子蛋白質有效的補充人體細胞和皮膚細胞的養份,增強機體活力和皮膚的彈性,修護鞏固基底層細胞組織達到去除皺紋、收緊毛孔、提升皮膚的顯著美容效果。5. we have found that cam and y - tubulin colocolized at the two sides of the midbody
本實驗中我們還觀察到在胞質分裂後期, cam與y一微管蛋白共分佈於中體兩端。The cell division element class plant growth regulator is one kind of promotion plant being of ability to promote the vegetable cell fission and the variation, delay the leaf blade senescence, promote lateral bud growth, break the apical dominance, induce injuries of the organization, split up the different organs and promote chloroplast growth and synthesis
細胞分裂素類植物生長調節劑是一種促進型植物激素,能夠促進植物細胞的分裂和變異,延緩葉片衰老;促進側芽發育,打破頂端優勢;誘導愈傷組織,分化成不同器官;促進葉綠體的發育和合成。Mr. li just participated worked, because frequently glances over the pornographic website, is stirred by the on - line pornographic content the spring tide to organ blister measles, are life - long cannot cure.
「安立克」的作用機理理論是:細胞和病毒的相對生存時間並不長久,機體細胞和病毒細胞的分裂再生過程一直在進行。3. when the cells were treated with w7, a ca2 + / cam inhibitor, the central spindle assembly was affected, and the abnormal central spindle was formed ; besides, when w7 treatment was applied at an early stage of cytokinesis, the division furrow index would decrease substantially. these results show that cam is really involved in the regulation of furrow formation and this involvement may be fulfilled by regulating the dynamic structure of central spindle
我們利用w7抑制cam活性,發現cam活性喪失會引起中區紡錘體結構異常;如用w7處理同步化于胞質分裂早期的細胞,可使細胞的分裂溝形成指數明顯下降,這表明cam的確參與調控了分裂溝的形成,而且可能是通過調控中區紡錘體的動態結構參與這一過程的。Sheep, mice, cattle, goats and pigs have been cloned, dolly - style, by transferring the nucleus of a cell from an adult animal into a hollowed - out egg. the success rate with cats was as low as with these animals. cc, born two months ago, was the only live birth from 87 cloned embryos that were implanted in surrogate mothers
