大多数生理功理是通过蛋白质及其相互作用来执行的,如收缩蛋白、激索,受体、酶和载体等.分子生物学技术可以帮助我们解释许多蛋白质的结构与功能方面的问题,而其它手段是无能为力的。通过对有意义的编码蛋白的基因克隆及其序列分析,人们可以推断相应蛋白质的氨基酸序列,从而建立与生理功能相关的分子结构模型。通过测定 mRNA 和蛋白质合成的数量,可以估价基因转录
Most physiological processes are performed through proteins and their interactions, such as contractile proteins, agonists, receptors, enzymes and vectors, etc. Molecular biology techniques can help us to explain the structural and functional aspects of many proteins, Other means are powerless. Through the gene cloning and sequence analysis of meaningful coding protein, one can deduce the amino acid sequence of the corresponding protein to establish the molecular structure model related to physiological function. By measuring the amount of mRNA and protein synthesis, gene transcription can be valued
