日常生活医学科普 The microtubules that make up the spindle network disappear, and a new nuclear membrane surrounds each haploid set. 组成纺锤体网络的微管消失,每组单倍体周围都有一层新的核膜。 2017级专外有声 The chromatin aggregates peripherally under the nuclear membrane, into well-delimited dense masses of various shapes and sizes. 细胞核本身可能崩解,产生两个或多个核碎片。 Osmosis-心血管 The capsid is covered by a protein layer called the tegument, and finally enclosed in an envelope, which is a lipid membrane that contains viral glycoproteins and is acquired from the nuclear membrane of host cells. 衣壳上覆盖有一层叫“间层”的蛋白,最外面由一层囊膜包裹;囊膜是一层包含病毒糖蛋白的磷脂膜,来自于宿主细胞的核膜。
中文百科
核膜![]() 核膜(英语:nuclear membrane 或 karyotheca),又称核被膜或核封套(nuclear envelope)是包围真核细胞细胞核,分隔开细胞核和细胞质的生物膜。 核膜由两层磷脂双分子层构成,厚度共约20-100nm。其中两层磷脂双层膜分别称作内核膜和外核膜,其中的空隙称作核周隙(核周腔,perinuclear space),其与内质网空腔是共通的。 外核膜向细胞质的一侧有核糖体附着,同时也可见到外膜与内质网膜有相连接的部位,因而使核周隙(perinuclear space)与粗面内质网腔相沟通。由于核膜与内质网膜是连续的,核膜可通过与内质网的流动而得以生长,迅速扩大或收缩(详见流体镶嵌模型) 。而这种内膜系统,磷脂双层膜的共有共通性正是将细胞核膜(或称核封套nuclear envelope)、内质网、高基氏体、溶体、液泡和细胞膜归类于内膜系统的原因。这些胞器的磷脂双层膜是可以较轻易共通的,且磷脂双层膜都是由内质网所制造的,而叶绿体与线粒体不被归类于内膜系统,即是因为膜来源不是来自内质网,且和其他的膜系统少有共有共通的现象。

Nuclear membrane 核膜![]() A nuclear membrane, also known as the nuclear envelope, nucleolemma or karyotheca, is the double lipid bilayer membrane which surrounds the genetic material and nucleolus in eukaryotic cells. The nuclear membrane consists of two lipid bilayers—the inner nuclear membrane, and the outer nuclear membrane. The space between the membranes is called the perinuclear space, a region contiguous with the lumen (inside) of the endoplasmic reticulum. It is usually about 20–40 nm wide. |
