Cell nucleus

... the nucleus. The outer membrane is continuous with the rough endoplasmic reticulum (RER) and may be studded with ribosomes . The space between the two ... with the lumen of the RER. Drawing of nucleus and the endoplasmic reticulum . (1) Nuclear envelope . (2) Ribosomes . (3) Nuclear pore complexes. ...

Endomembrane system

... is the membrane around the nucleus of the cell. The endoplasmic reticulum is a synthesis and transport organelle [the endoplasmic reticulum is an extension of the nuclear envelope]. The Golgi apparatus acts as ...

Ribosome

... fluid of the cell) or bind to another organelle called the endoplasmic reticulum . Since ribosomes are ribozymes , it is thought that they might be ... associated with the membrane of the nucleus and the rough endoplasmic reticulum (in eukaryotes only) for the time of synthesis. They insert the freshly ...

Vesicle

... vesicles are made in the Golgi apparatus , but also in the endoplasmic reticulum , or are made from parts of the plasma membrane . Lysosomes ... between locations inside the cell, e.g., proteins from the endoplasmic reticulum to the Golgi apparatus, and from there to the outer cell membrane, where ...

Cisterna

... earliest cisternae are called the cis-cisternae, followed by the medial cisternae, then the trans-cisternae (as they move away from the endoplasmic reticulum ). The formation of new cisternae is often called the cis-Golgi network and at the end of the Golgi where transport to other parts of the cell ...

Eukaryote

... pores that allow material to move in and out. Various tube- and sheet-like extensions of the nuclear membrane form what is called the endoplasmic reticulum or ER, which is involved in protein transport. It includes rough sections where ribosomes are attached, and the proteins they synthesize enter ...

Neuron

... of Nissl substance (named after German psychiatrist and neuropathologist Franz Nissl , 1860–1919), which consists of rough endoplasmic reticulum and associated ribosomes . The prominence of the Nissl substance can be explained by the fact that nerve cells are metabolically very active, and ...

Organelle

Prokaryote

... of a nucleus or nuclear envelope . Prokaryotes also lack cytoskeletons and membrane-bound cell compartments such as vacuoles , endoplasmic reticulum , mitochondria and chloroplasts . In eukaryotes, the latter two perform various metabolic processes and are believed to have been derived from ...

Protein biosynthesis

... modifications are required for the newly transcribed mRNA to be able to travel to the other parts of the cell, including cytoplasm and endoplasmic reticulum . A 5’ cap is added to the mRNA to protect it from degradation. A poly-A tail is added on the 3’ end for protection and as a template ...

Trait

... may also be followed through the Cell as it travels from the DNA in the Nucleus , to the Cytoplasm , to the Ribosomes and the Endoplasmic reticulum , and finally to the Golgi Apparatus , which may package the final products for export outside the cell. Cell products are released into the ...

Virus

... together. The new viruses then leave the cell either by exocytosis or by lysis . Envelope-bound animal viruses instruct the host's endoplasmic reticulum to make certain proteins, called glycoproteins , which then collect in clumps along the cell membrane. The virus is then discharged from the cell ...
