Assembles protein - Study guides, Class notes & Summaries

Structure of Nucleus. - Answer 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucl...

Binary Fission 1. Growth of cell size and increase in cell components 2. Replication of DNA 3. Division of the cytoplasm (cytokinesis) 4. Septum formation and division of daughter cells Binary fission step 1 (1. Growth of cell size and increase in cell components) "The most common mechanism of cell replication in bacteria is a process called binary fission, ; Before dividing, the cell grows and increases its number of cellular components." Calculating Number of Cells "The number of cells in...
