终止信号

TCS基因下游为转录终止信号。

A transcription termination signal was found downstream of TCS gene .

酶切鉴定、PCR鉴定和测序结果表明，成功获得了TK基因，获得的TK基因内存在一个KpnⅠ酶切位点和编码区的早期转录终止信号TTTTTN（T）T。

Restriction enzyme assay , PCR and sequencing confirmed that the TK gene was obtained successfully . Only one Kpn ⅰ site and a transcription termination signal TTTTT N ( T ) T were found in the gene .

提供转录终止信号的DNA顺序称为终止子。

The DNA sequence that provides the signal to cease transcription is called a terminator .

方法：用PCR法从绿脓杆菌基因组DNA中克隆PEAⅡ＋Ⅲ区基因，引入Kozak序列、终止信号和酶切位点，测序。

Methods : Polymerase Chain Reaction was employed to clone PEA domain ⅱ + ⅲ structural gene , introducing Kozak sequence , termination code and restriction sites .

在设计的靶序列5′端开始的19个核苷酸为正义链，中间加入9个核苷酸TTCAAGAGA的间隔以形成发夹结构，3′端加有转录终止信号TTTTTT。

The sense strand of siRNA was composed of the start 19 nucleotides of the 5 ' end of target sequence .

第一类释放因子是新生肽链释放所必需的因子，它能正确地识别终止信号，水解肽酰tRNA酯键，释放出新合成的多肽链。

The class 1 release factor is required in termination of protein synthesis . It could accurately recognize the stop signal and promotes the hydrolysis of the ester bond linking the polypeptide chain with the peptidyl ( p ) site tRNA .

泛素化作用是细胞内存在的负向调控因子抑制或终止信号蛋白表达的主要机制之一。

Ubiquitination is one of the major mechanisms of inhibit or termination of signal protein which is regulated by negative regulatory factors .

蛋白磷酸酶与蛋白激酶作为一对开关调控细胞内的一系列生化反应，蛋白磷酸酶可以催化去磷酸化反应，使磷酸化的蛋白质脱磷酸化，终止信号分子的传递，从而调控细胞信号转导通路。

Protein phosphatase catalyzed dephosphorylation reaction , so that protein phosphorylation and dephosphorylation , terminate the transfer of signaling molecules , and thereby regulate cell signaling signal transduction pathway .

软件测试提高软件的可靠性；软件可靠性的评估可以为软件测试提供合理的终止信号。

There are strong and natural relations between them : software test improve the software reliability , in turn the accurate evaluation on software reliability can provide reasonable stopping signal of software test .

包括8个点突变（6个错义突变，1个静息突变和1个内含子突变）和1个碱基对插入突变（在下游产生终止信号）。

All of them have been characterized to represent DNA alterations by sequencing , including 8 point mutations ( 6 missence , 1 silent mutation and 1 in intron ) and a 1 base pair insertion ( introducing a stop codon downstream ) .

一般来说RGS可加速G蛋白失活进而终止GPCR信号传导，但也有些RGS同时具有效应分子和信号传递功能。

RGS proteins accelerate the deactivation of G proteins to reduce GPCR signaling ; however , some also have an effector function and transmit signals .

控制器通过检测器获得的各车道交通流量和排队长度来判断各个相位的交通强度，进而决定是否延长或终止当前的信号相位。

The controller got flows and queues from its detectors to estimate traffic intensity , which was then used to determine whether the current signal phase should be extended or terminated .

稍后您将看到进程如何trap信号而使终止失败，但是这里我们将使用终止信号（SIGINT）来终止时钟。

Later in this tip you see how a process can trap signals and not terminate , but here you use the interrupt signal ( SIGINT ) to terminate the clock .

可以通过信号机制终止脚本（注意，并不是所有发送的信号都是终止信号）。

Scripts can be killed or terminated using the signal mechanism ( note that not all signals sent are terminal ) .
