How do yeast control the expression of their genes? And how is this relevant to beer and wine fermentation? On this page we’ll dive into the details of gene expression regulation, and learn how specific DNA sequences, called promoters, can impact the flavor of fermented beverages. 酵母是如何控制它们基因的表达的?这与啤酒和葡萄酒发酵有什么关系呢?在本页中，我们将深入研究基因表达调控的细节，并了解称为启动子的特定DNA序列如何影响发酵饮料的风味。 What is a promoter? 什么是启动子？The DNA that makes up every gene can be divided into different functional segments (Figure 1). One segment, called the “coding sequence”, contains the information necessary for producing a protein. A second segment, called the promoter, is located next to the coding sequence and determines precisely when the gene will be expressed, and how many proteins will be produced from it. Essentially, a promoter is responsible for sens
