  • 1

    Where is the starting point of replication, the origin, located?

    Close to the binding site of the chromosome to the plasma membrane

  • 2

    In what direction does DNA replication occur?

    Bidirectional—moving away from the origin on both strands of the DNA loop simultaneously

  • 3

    What happens to the origin points as the new double strands are formed?

    They move away from each other toward opposite ends of the cell

  • 4

    What aids in the transport of the chromosomes as the cell elongates?

    The growing membrane

  • 5

    What is formed between the nucleoids as cytoplasmic separation begins?

    A septum

  • 6

    Where does replication of the circular prokaryotic chromosome begin?

    At the origin of replication

  • 7

    In which directions does replication of the circular prokaryotic chromosome continue?

    In both directions at once

  • 8

    What happens to the cell as replication begins?

    It begins to elongate

  • 9

    What forms a ring around the periphery of the midpoint between the chromosomes?

    FtsZ proteins

  • 10

    What is the result of the formation of the septum?

    The cell pinches in two, forming two daughter cells

  • 11

    Why is the precise timing and formation of the mitotic spindle critical?

    For the success of eukaryotic cell division

  • 12

    Do prokaryotic cells undergo mitosis?

    No

  • 13

    What is the FtsZ protein in prokaryotic cells similar to?

    Tubulin

  • 14

    What are the microtubules that make up the mitotic spindle fibers composed of?

    Tubulin

  • 15

    What directs the partition between the nucleoids in prokaryotes?

    A ring composed of repeating units of a protein called FtsZ

  • 16

    What triggers the accumulation of other proteins to recruit new membrane and cell-wall materials?

    The formation of the FtsZ ring

  • 17

    What type of structures can FtsZ proteins form?

    Filaments, rings, and other three-dimensional structures

  • 18

    What energy source do both FtsZ and tubulin employ to assemble and disassemble complex structures?

    GTP (guanosine triphosphate)
