The nucleus is separated from the cytoplasm by a nuclear membrane consisting of two parallel lipoprotein unit membranes that are 7–8 nanometers (nm) thick and have a narrow perinuclear space between them. The nuclear membrane is perforated by pores measuring 60–100 nm in diameter; the outer ...

The nucleus provides a site for genetic transcription that is segregated from the location of translation in the cytoplasm, allowing levels of gene regulation that are not available to prokaryotes. The main function of the cell nucleus is to control gene expression and mediate the replication of DN...
aThe nucleus is a compact sphere that is the most prominent organelle of eukaryotic cells. It is separated from the cell cytoplasm by an external boundary called a nuclear envelope. 中坚力量是eukaryotic细胞最突出的细胞器的紧凑球形。 它从细胞细胞质被分离由称一个核信封的一个外在界限。 [translate]...
Eukaryotic genomes are distributed on linear chromosomes that are grouped together in the nucleus, an organelle separated from the cytoplasm by a characteristic double membrane studded with large proteinaceous pores. The chromatin within... A Taddei,F Hediger,FR Neumann,... - 《Nuclear Organization ...
1704年,“坚果的核心”; 1708年,“彗星的头部”; 源自拉丁语 nucleus “核心”,源自 nucula “小坚果”,是 nux(属格 nucis)“坚果”的小型形式,源自 PIE *kneu- “坚果”(源头还包括中古爱尔兰语 cnu,威尔士语 cneuen,中古布列塔尼语 knoen “坚果”,古诺尔斯语 hnot,古英语 hnutu “坚果”)。

The nucleus obtains structural support through the nuclear lamina, which is attached to the nuclear double membrane, together forming the nuclear envelope (Fig. 1) The nuclear envelope controls traffic of molecules between the cytoplasm and the nucleoplasm but has also emerged as a critical ...
The IMPβ-RanGTP complex is subsequently recycled to the cytoplasm, while IMPα is exported from the nucleus by the IMPβ homologue CAS, as complexed with RanGTP [27]. Once in the cytoplasm, the action of RanGAP catalyzes the hydrolysis of GTP to GDP, resulting in the dissociation of ...
The nucleus in the cell is the organelle that stores DNA. The nucleus' job is to store DNA and keep it safe and separated from the rest of the cell. What are the 4 major functions of the nucleus? The four major functions of the nucleus are to: Store DNA and protect it from the ...
