TIRAP is an adapter molecule associated with toll-like receptors (TLRs) of the immune system, which identify pathogen-associated molecular patterns. This protein is involved in the TLR4 intracellular signaling pathway. It activates NFkB, MAPK1, MAPK3 and JNK, which then result in cytokine secretion and the inflammatory response. 附件tirap.fasta是人Homo sapiens、猕猴Macaca fascicularis、大象Loxodonta africana、马Equus caballus、鸡Gallus gallus、袋獾Sarcophilus harrisii、爪蟾Xenopus tropicalis、河豚Takifugu rubripes、剑尾鱼Xiphophorus maculatus、斑马鱼Danio rerio十个物种的TIRAP蛋白质序列。请用MEGA7为这些序列构建一株NJ树。MEGA7用ClustalW方法做出的多序列比对结果截图(1分)。参数设置页面截图:步长检验(BOOTSTRAP)取值100,其他参数默认(1分)。构建出来的Original Tree截图(1分)。构建出来的Bootstrap consensus tree截图(1分)。说出Original Tree和Bootstrap consensus tree树枝的长短有什么区别(1分)。
War has escaped the battlefield and now can, with modern guidance systems on missiles, touch virtually every square yard of the earth‟s surface. War has also lost most of its utility in achieving the traditional goals of conflict. (1)Control of territory carries with it the obligation to provide subject peoples certain administrative, health, education, and other social services; such obligations far exceed the benefits of control. If the ruled population is racially different from the rulers, tensions and constant unrest often exist which further reduce the benefits and increase the costs of domination. (2)Large populations no longer necessarily enhance state power and, in the absence of high levels of economic development, can impose severe burdens on food supply, jobs, and the broad range of services expected of modern governments.
