Binary fission - Guides d'étude, Notes de cours & Résumés

Eukaryotes - ANSWER multicellular, complex organisms, have a proper nucleus containing genome, and organelles (lysosomes, endoplasmic reticular - smooth and rough - golgi complexes, and mitochondria), DNA = contained in multiple linear chromosomes, cells divide using MITOSIS Prokaryotes - ANSWER primitive organisms, much smaller cells, unicellular, no nucleus, genome = in nucleoid, no organelles, DNA = contained in single circular chromosome, cells divide using BINARY FISSION binary ...

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...

Binary Fission Correct Answer Cell division in bacteria in which one cell divides into two cells Why do bacterial cells not undergo mitosis and meiosis? Correct Answer 1) Prokaryotic cells do not possess the machinery to produce spindle fibers and therefore cannot move chromosomes around in the cell 2) Replication of DNA in a prokaryote does not occur in one phase, but instead occurs continuously 3) Most bacteria have only one circular chromosome that is attached to the cell membrane Bac...

AP Biology Exam (units 5-8) Latest Version Graded A+ 10% rule Only 10% of the total energy produced at each trophic level is available to the next level. The amount of energy passed up to the levels of the food pyramid reduces as you go up. 3' vs 5' end of DNA strand replication goes 3'->5' - 3' (of original molecule) is leading strand - 5' is lagging strand adaptive immunity the ability to recognize and remember specific antigens and mount an attack on them altruism ...
