The karyotype of caragana microphylla lam can be espressed as 2n = 16 = 16m ( 4sat ) ; the chromosome number of c. intermedia kuang et h. c. fu is 2n = 18. the karyotype of c. intermedia kuang et h. c. fu can be espressed as 2n = 18 = 16m ( 4sat ) + 2m ; the chromosome number of c. arborescens ( amm. ) lam is 2n = 20. the karyotype of c. arborescens ( amm. ) lam can be espressed as 2n = 20 = 20m ( 4sat ) ; from the conclusion one and two, we can guess : the c. intermedia kuang et h. c. fu ' may be the hybrid or intermediary genve between caragana microphlla lam and c. arborescens ( amm ) lam, also may be have different haploid chromosome number
( 2 )可得出三種染
色體核型:小葉錦雞兒的染
色體數為2n = 16 ,其核型公式為2n = 16 = 16m ( 4sat ) ;中間錦雞兒的染
色體數為2n = 18 ,其核型公式為2n = 18 = 16m ( 4sat ) + 2m ;樹錦雞兒的染
色體數為2n = 20 ,其核型公式為2n = 20 = 20m ( 4sat ) ,結合形態學所得結論,可推測:中間錦雞兒為小葉錦雞兒和樹錦雞兒的中間類型或雜交種,也可能是具有遞增染
色體基數的不同種。
After amniocentesis and prenatal counseling, the couple chose to terminate the pregnancy
經羊膜穿刺術檢查染
色體正常。
Karyotyping for adanced maternal age was performed by amniocentesis and demonstrated a normal male karyotype ( 46 xy with g - banding )
對此高齡孕婦行羊膜穿刺染
色體組型分型檢查,先是正常男性( 46xy , g帶顯帶技術) 。
In this paper, the karyotype and banding pattern of amphioxus b. belcheri tsingtauense were reported for the first time
本文首次報道了青島文昌魚染
色體的核型和帶型。
It has been more than 100 years since the first description of the chromosomes of the amphioxus branchiostoma lanceolatum by stricht in 1895
自stricht1895年報道文昌魚的染
色體以來,迄今只報道了branchiostomalanceolatum 、 b
During anaphase i of meiosis pairs of chromatids still connected at their centromere move to the spindle poles
在減數分裂後期i中,由於紡錘絲的牽引,使成對的同源染
色體各自發生分離,並分別向兩極移動。
In addition to avermectins, s. avermitilis produces oligomycin, a strongly toxic compound. gene deletion vector pxl05 was used to disrupt oligomycin polyketide synthase ( pks ) encoding genes ( olma ) in streptomyces avermitilis cz8 - 73, the producer of anthelmintic avermectins b and the cell growth inhibitor oligomycin. olma gene cluster in the chromosome was displaced by deletion allele on the plasmid via double crossover
本研究以產阿維菌素b和寡黴素的阿維鏈黴菌cz8 - 73為出發菌株,構建了基因缺失載
體pxl05 ,並將其轉入cz8 - 73中,通過缺失載
體和染
色體之間的同源雙交換,對染
色體上長達90kb的寡黴素聚酮合酶( pks )基因簇( olma )進行了缺失。
The chromosome number and analysis of karyotype of antirrhinum manjus l
金魚草染
色體數目及核型分析
Genes located on these chromosomes do not assort independently of sex and are said to be sex-linked.
這些染
色體上的基因不能離開性別而自由組合,稱為性連鎖。
Human x and y chromosomes behave differently from the autosomes.
人的X和Y染
色體跟常染
色體有不同的活動。
Human x and y chromosomes behave differently from the autosomes
人的x和y染色體跟常染色體有不同的活動。
