Document Summary
Nucleoid (see fig 6. 5): region where dna is concentrated, yet not membrane-enclosed, in prokaryotes. Cytoplasm: is the area in which the cytosol is; area between nucleus and plasma membrane. 6. 6): phospholipid bilayer, which functions as a selective barrier that allows passage of enough oxygen, nutrients, and wastes to service the entire cell. >>>>>the nucleus contains the cell"s genetic library (see fig. Nucleus: contains most of the genes in eukaryotes. Chromatin: the complex of dna and proteins that make up eukaryotic chromosomes: appears long and thin (when cell is not dividing) Chromosomes: structures that carry the genetic information: contains one long dna molecules associated with many proteins. Nucleolus: a specialized structure in the nucleus, consisting of chromosomal regions containing ribosomal rna genes along with ribosomal proteins imported from the cytoplasm: site of rrna synthesis and ribosomal subunit assembly. >>>>>many cell organelles are connected through the endomembrane system. All of the components are related either directly or indirectly.
