1. What are the gene expression stages that can be regulated? (10 points) Regulated stages in gene expression: (1) transcription initiation (the most important stage): RNAP binding of the promoter, transition from the closed complex to the open complex; promoter escape 4’ (2) stages after initiation (elongation and termination) 2’ (3) RNA processing (alternative splicing) in eukaryotes 2’ (4) translation 2’

The Europeanisation of private law is very much a topical theme. And although this theme no longer very new, it has, in the last three years, developed a new dynamic. Anyone taking it up with the intention or hope of keeping up with the pace of legal policy development and remaining on top of the current stage of the academic debate is letting himself in for a race in which he will inevitably feel like the unfortunate hare which, despite all its efforts, kept on

If the global economy falters, free trade will suffer \I'M MAD as hell, roared the man on stage. \Mad as hell about what is happening to the manufacturing sector in America. \ This is a trade war with China,\ shouted his colleague, \and it's time to fight that war head on.\ The audience cheered in approval. Patriotic songs played in the background, interspersed with extracts from George Bush's address to the nation after September

一、序惯博弈(sequential game):参与人在前一个决策点的选择决定随后的子博弈的结构,因此,从后一个决策点开始的子博弈不同于从前一个决策点开始的子博弈,或者说,同样结构的子博弈只出现一次; 二、重复博弈(repeated game):同样结构的博弈重复多次,其中的每次博弈被称为“阶段博弈” (stage game)

ipids differ from the other classes of naturally occurring biomolecules (carbohy- drates, proteins, and nucleic acids)in that they are more soluble in non-to-weakly polar solvents(diethyl ether, hexane, dichloromethathan they are in water.they include a variety of structural types, a collection of which is introduced in this chapter. In spite of the number of different structural types, lipids share a common biosyn- thetic origin in that they are ultimately derived from glucose. During one stage of car- bohydrate metabolism, called glycolysis, glucose is converted to lactic acid. Pyruvic acid is an intermediate
