The colonization of land by eukaryotes isthought to have been established through the symbiosis of a fungus and aphotosynthesizing organism ( gehrig et al . 1996 ; heckman et al . 2001 ) 经过真菌和光合生物的共生使真核生物在陆地上集群已经被认为确立。
Actin , the major component of the dynamic microfilaments system , exists in nearly all eukaryotic cells , and plays an essential role in living activities 肌动蛋白在真核生物中广泛存在，由肌动蛋白参与形成的动态微丝骨架系统是细胞生命活动的基础。
The packaging of eukaryotic dna into chromatin influences various processes that utilize dna as a template , including transcription , replication and repair 真核生物dna紧密包装成染色质结构，影响了包括转录、复制和修复等在内的以dna为模板的每一个生物过程。
Actin , the major component of the dynamic microfilament cytoskeleton system , exists in nearly all eukaryotic cells and plays essential roles in cellular activities 摘要肌动蛋白在真核生物中广泛存在，由肌动蛋白参与形成的动态微丝骨架系统是细胞生命活动的基础。
All eukaryotes ( organisms with nuclei in their cells ) use a molecular translator enzyme called rna polymerase ii to read the genes that are expressed into proteins 所有的真核生物（细胞里有核的生物体）利用一种称为rna聚合酶ii的分子转录酵素，来读取蛋白质的基因。
D . salina can grow in extreme environment such as in a variety of salt concentrations ranging from 0 . 05m to 5m , and the optimum salt concentration for growth is 2m to 3m 该藻的突出优点在于抗逆性极佳，可在0 . 05m - 5m的盐水中生长，最佳生长繁殖盐度为2 - 3m ，是目前已知最耐盐的真核生物。
The study on the relationship between the acetylation and hsp gene transcription regulation will help us in understanding the mechanisms of eukaryotic transcription regulation 因此，对乙酰化与热休克蛋白基因表达调控关系的深入研究，将有助于我们对乙酰化参与的真核生物基因表达调控的理解。
In eukaryotes , it is very clearly that map kinase ( mitogen - activated protein kinase ) signal transduction pathways are important routes for the channelling of extracellular stimuli to cytoplasm or nucleus 在真核生物中， map激酶信号转导途径是一种重要的传递外界刺激到细胞质或细胞核的方式。
Dunaliella . salina , a single - celled eukaryotic organism , has a relatively simple mechanism of saturation regulation , therefore it is an ideal model organism to be used to study the mechanism of salt stress tolerance 盐藻是真核生物，呈细胞结构，因此渗透调节机制相对简单，对耐盐机理研究可能是一种理想的材料。
During the long - term evolution an integrated regulation system , which is highly conserved in eukaryotes from yeast to homo sapient , has developed to regulate copper transportation and homeostasis 在长期进化过程中真核生物形成了一套完整的铜转运和稳态调节系统，从酵母到灵长类的各种生物都具有高度同源性的调控组件。
