從文昌魚染色體的核型看,似乎形態較小的端部著絲粒染色體是脊椎動物染色體的遠祖。He mused over the incident after she had gone, and once or twice broke out into laughter that was bitter as he saw his sister and her betrothed, all the members of his own class and the members of ruth s class, directing their narrow little lives by narrow little formulas - herd - creatures, flocking together and patterning their lives by one another s opinions, failing of being individuals and of really living life because of the childlike formulas by which they were enslaved
妹妹離開之後他考慮了一下這事,不禁一再苦笑。他看見妹妹和她的未婚夫工人階級的全部成員還有露絲那階級的全部成員,人人都按照自己渺小的公式過著自己的狹隘生活他們是過著集體生活的群居動物,他們用彼此的輿論塑造著彼此的生活。他們受到那些奴役著他們的幼稚公式的控制,都不再是單個的個人,也都過不到真正的生活。The concentration of 0. 0375 % is better than th at of 0. 075 %. the conclusion can be drawn according to the observation of 517 clear metaphases of mitosis that the number of diploid chromosome is 2n = 42 and the karyotype formula is 42t, nf = 42. a special huge chromosome was observed in a part of larval fish
通過對517個清晰的中期分裂相的觀察和統計,最終確定:半滑舌鰨的半滑舌姻的早期胚胎光聰觀察及核型研究染色體眾數zn ? 42 ,臂數nf二42 ,核型為42t ,全部為端部著絲粒染色體。This showed that the diploid chromosome number ( 2n ) of amphioxus b. belcheri tsingtauense was 36. the chromosomes were extremely small, ranging from 1. 4 to 3. 7 um in length. the first pair of the 36 chromosomes of b. belcheri tsingtauense was subtelocentric and the other 17 pairs telocentric. neither metacentric nor submetacentric chromosomes nor satellites were observed
