Assembles protein - Study guides, Class notes & Summaries

• DNA = phosphate + deoxyribose sugar + A/T/C/G o Contains two strands. The strands are antiparallel (opposite each other). o 5’ → 3’ 3’ ← 5’ • RNA = phosphate + ribose sugar + A/U/C/G o Single strand, can fold back onto itself and form pairs between itself (stem‐loop). • Each nucleic acid is made up of polymers (many monomers) that are called nucleotides. o Nucleotides contain one or more phosphates, a five‐carbon sugar, and a nitrogen base. o Nucleotides are alway...

Structure of Nucleus. 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 Nucleus. 1. Controls...

Binary Fission Most common form of bacterial reproduction Binary fission 4 Basic steps 1. Growth of cell size and increase in cell components 2. Replication of DNA 3. Division of Cytoplasm (cytokinesis) 4. Septum formation and division of daughter cells Fstz 1. Cytokinesis is directed by this protein 2. Assembles Z ring to form (Divisome) What activates the production of a peptidoglycan and septum? Divisome Generation (Doubling Time) Time takes to double population through one round of binar...

Exocytosis - Answer release of substances out a cell by the fusion of a vesicle with the membrane. Endocytosis - Answer Uptake of materials into the cell Endocytosis: Pinocytosis - Answer "Cell drinking" Endocytosis: Phagocytosis - Answer "Cell eating" Cell Membrane "Plasma Membrane" - Answer Surrounds the cell Composed of phospholipid & protein Semi-permable - Answer provides a selective barrier that regulates transport of substances into and out of the cell. Cytoplasm ...
