近年来,酵母菌作为一种简单的真核微生物,在分子生物学上得到了深入研究。因为它既具有一般微生物易培养、生长快、易操作等特点,在遗传结构等方面也与大肠杆菌等原核微生物有许多相似之处。而更重要的是:酵母菌是一种低等真核生物,它具有一般真核生物所具有的基本特点。如细胞核结构,染色体结构,线粒体结构,有丝分裂和减数分裂现象等方面都与真核生物类似。所以,以酵母为材料来研究真核生物的一些基本生物学问题是非常理想的。也正因为它兼有原核生物和真核生物的特点,又没有
In recent years, yeast as a simple eukaryotic microorganism, has been in-depth study of molecular biology. Because it has the characteristics of easy cultivation, rapid growth and easy operation of common microorganisms, it has many similarities with prokaryotic microorganisms such as Escherichia coli in genetic structure and the like. And more importantly: Yeast is a lower eukaryote, which has the basic characteristics of the general eukaryotes. Such as the nuclear structure, chromosome structure, mitochondrial structure, mitosis and meiosis and other aspects of eukaryotes are similar. Therefore, the yeast as a material to study some of the basic biological problems of eukaryotes is very desirable. It is also because it combines the characteristics of prokaryotes and eukaryotes, but not
