NATS 1670 Lecture Notes - Lecture 35: Nuclear Membrane, Nuclear Pore, Nucleolus
Document Summary
Are the cells" garbage disposal system, the clean-up crew . Breaking down molecules into their base components using strong digestive enzymes. Outer membrane, inner membrane, rough er, chromatin, nucleolus, nuclear pore. The nucleus, the largest organelle, contains the dna, rna, proteins. The dna is packed into chromosomes, an assembly of dna and proteins. The nuclear envelope surrounding the nucleus consists of two membranes. This envelope has large pores that allow rna and other macromolecules to leave or to enter the nucleus. On the inner surface there are attachment sites for the dna molecules. The nucleolus is a spherical body located within the nucleus that contains primarily rna and proteins. A infectious disease which was derived from the west that in most cases has no symptoms. It was caused by a virus, which invades the nervous system. This disease can invade the brain and spinal cord, which can lead to paralysis, disability or death.
