homologous chromosome 中文意思是什麼

homologous chromosome 解釋
對應染色體
  • homologous : adj. 1. 同源的。2. 【生物學】異體同型的。3. 【化學】同系列的；同屬列的；同周期的。4. 【醫學】同源的。5. 【醫學】＝ homoplastic.
  • chromosome : n. 【生物學】染色體。
  1. Aneuploidy the condition, resulting from nondisjunction of homologous chromosomes at meiosis, in which one or more chromosomes are missing from or added to the normal somatic chromosome number

    非整倍性：在減數分裂的過程中同源染色體不分離而造成的一條或多條染色體的缺失或增加。
  2. 4. engineering dhqase ( arod ) - deficient e. coli mutant with a second copy of the arob gene gene targeting technique was used to disrupt the arod gene in e. coli chromosome. the mutant 31bk was engineered, in which homologous recombination of the arobkanr gene cassette into the arod locus ( arod : : arobkanr ) of the e. coli strain atcc31884 genome utilized the helper plasmid pkd46 with red system. the host cell 31bk lacked catalytic activity of dhqase ( arod ) and had a second copy of the arob gene, so it improved carbon flow into the quinic acid biosynthesis direction

    構建宿主菌基因精確定位突變株31bk （ arod : : arobkan ~ r ）為了改變代謝途徑脫氫奎尼酸（ dhq ）分支點上的代謝流量，使之充分流向目的產物奎尼酸合成方向，利用基因打靶技術構建了31884宿主菌arod基因精確定位插入突變體，使dhq脫水酶（ dhqase ）失活，阻斷了碳代謝流流向芳香氨基酸生成的方向，同時用同源重組的方法將arob基因定位整合入染色體上，解除了限速酶對碳代謝流通過共同途徑到達dhq的阻遏影響，並減輕代謝負擔。
  3. Translocation occurs when a fragment of one chromosome becomes attached to a non-homologous chromosome.

    一段染色體跟非同源染色體連在一起時就發生易位。
  4. An aneuploid state in which a third homologous chromosome is present in addition to the normal autosomal pair is called trisomy.

    除了正常染色體對以外，還存在有第二種同源染色體的非整倍體狀態，被稱為三體性。
  5. Non - homologous chromosome

    異源染色體
  6. Locus ( pl. loci ) the position of a gene on a chromosome. alleles of the same gene occupy the equivalent locus on homologous chromosomes

    基因位點，基因座：基因在染色體上的位置。等位基因位於同源染色體相對應的位點上。
  7. Pairing of homologous chromosomes ( synapsis ) commences at one or several points on the chromosome and is clearly seen during pachytene of meiosis i

    同源染色體兩兩成對平行靠攏，這一現象也稱聯會，聯會發生在染色體的一點或多點上，可以在減數第一次分裂的粗線期觀察到。
  8. 8kb cdna with 1362bp orf and codes 454 amino acids with only a sh2 domain. the gene was named as sh2a at chromosome 8p22. we study its structure by blast homologous analysis and its expression by rt - pcr and northern blot

    本文將通過蛋白質分析軟體研究其結構和同源性，利用rt - pcr和northern印跡雜交技術研究該基因的表達情況及該基因與腫瘤的關系。
