In this talk, I use cases from biology and ecology to argue that meta-analysis has another, under-explored epistemic virtue. It allows scientists to better understand the causes and consequences of variation in a body of evid...
Sanger sequencing is a method that yields information about the identity and order of the four nucleotide bases in a segment of DNA. Also known also as the “chain-termination method”, it was developed in 1977 by Frederick Sanger and colleagues, and ...

早在1991年,Robin Lovell-Badge教授带领的团队发现了哺乳动物Y染色体上的性别决定基因Sry[2]。这个基因编码的蛋白叫做性别决定区域Y蛋白(SRY),也叫做睾丸决定因子(TDF). 2004年发表在Developmental Biology期刊上的文章证实在Sertoli细胞前体中,SRY上调SOX9的...

摘要: Flux balance analysis is a mathematical approach for analyzing the flow of metabolites through a metabolic network. This primer covers the theoretical basis of the approach, several practical examples and a software toolbox for performing the calculations....
根据第二段第二句“This is a practical science course based on biology, which prepares people to work in those fields which combine biology and chemistry.”(这是一门实际的科学课程,建立在生物的基础上。可以让人们准备在结合生物和化学这两个学科的领域工作。)故此句是错误的。2. 【答案】T【解析】...
