HeterogeneityofSingleCellGeneExpressionAcrossPhenotypically(一)

Introduction Multi-cellular populations are fundamentally driven by the collective properties of individual cells. However, our understanding of gene expression dynamics derived from cultures or tissues is based on measurements made from the entire population. A growing body of data collected from individual cells has challenged these basic assumptions. The data suggest that ......阅读全文

克隆基因的表达(expression-of-cloned-gene)1

基因表达(gene expression)是指储存遗传信息的基因经过一系列步骤表现出其生物功能的整个过程。典型的基因表达是基因经过转录、翻译,产生有生物活性的蛋白质的过程。基因的表达主要涉及到两个过程:转录和翻译。   第一节影响外源基因表达的因素 利用基因工程技术高水平表达

克隆基因的表达(expression-of-cloned-gene)3

(3)原核生物的基因组基本上是单倍体,而真核基因组是二倍体。(4)如前所述,细菌多数基因按功能相关成串排列,组成操纵元的基因表达调控的单元,共同开启或关闭,转录出多顺反子(polycistron)的mRNA;真核生物则是一个结构基因转录生成一条mRNA,即mRNA是单顺反子(monocistron)

克隆基因的表达(expression-of-cloned-gene)2

在双链 DNA 分子中,只有一条链转录成 mRNA,这条链称为有意义链(sense strand),该基因的另一条链则称反意义链(antisense strand)。在含有许多基因的 DNA 双链中,每个基因的有意义链并不是在同一条 DNA 链上。也就是说,一条链上既具有某些基因的有意义链,

“基因”(Gene)一词是怎么来的?

  基因所代表的物质在生命中至关重要,它的发现是科学史一个伟大的里程碑。“基因” 这个词的发明和翻译也堪称完美。  对科学名词的翻译的方式有两种,一种是意译(根据含义来翻译),另一种是音译(根据读音来翻译)。能在意译和音译上都达标则效果更佳,但这样的名词极少,一个难得的例子是 “基因”(Gene
