In general, a eukaryotic cell has only one nucleus. However, some eukaryotic cells are enucleated cells (without a nucleus), for example, red blood cells (RBCs); whereas, some are multinucleate (consists of two or more nuclei), for example, slimemolds. The nucleus is separated from the re...
Step 1: Structure of the Nucleus- The nucleus is a spherical or oval-shaped organelle found in eukaryotic cells.- It is surrounded by a double-layered membrane called the nuclear membrane or nuclear envelope.- The nuclear membrane has nuclear pores that allow the exchange of materials between ...
Nuclear pore complex (NPC) constitutes the only regular route of cargo transport between the cytoplasm and the nucleus.1,2 NPC resides on the nuclear envelope (NE) of all eukaryotic cells. Although the size and composition of the NPC may vary across species,3,4,5,6,7 the overall organizati...

Like all animal cells, each neuron is bounded by a cell membrane that encloses the contents of the cell鈥攖hat is, the cytoplasm (cell fluid) and the nucleus. The size and shape of these neurons vary widely, but the structural plan always includes certain elements (Fig. 1-1): a cell...
The herpesviruses replicate in the nucleus and the nucleocapsid assembles in the nucleus; in this case, the first budding event is through the nuclear membrane (Fig. 2.25A). Download: Download full-size image FIGURE 2.25. Gallery of budding figures of viruses representing several different ...
Rutherford’s model required that the electrons be in motion. Positive and negative charges attract each other, so stationary electrons would fall into the positive nucleus. Also, because both the electrons and the nucleus are extremely small, most of the atom is empty, which is why nearly all...

The nuclear pore complex (NPC) is the only route of bidirectional cargo transport between the cytoplasm and the nucleus in a eukaryotic cell. With an estimated molecular mass of about 110–125 MDa in higher eukaryotes, NPC is among the largest and most important cellular machineries.1,2,3,4...
Varicella-zoster virus (VZV), a member of the Alphaherpesvirinae subfamily, causes severe diseases in humans of all ages. The viral capsids play critical roles in herpesvirus infection, making them potential antiviral targets. Here, we present the 3.7-
