Cell Cycle Flashcards
During which phase of mitosis do chromosomes first become visible?
Prophase
Which of the following lists the stages of the cell cycle in the correct order?
Interphase, prophase, metaphase, anaphase, telophase
Which portion of the cell cycle immediately follows after replication of DNA?
Gap 2 (G2)
During which phase of mitosis do the chromosomes align in the center of the cell?
Metaphase
During which part of the cell cycle does the cell grow and do its normal work?
Interphase
During which part of the cell cycle does DNA replication occur?
Interphase
Interphase
Meiosis produces 4 cells with 23 chromosomes each; mitosis produces 2 cells with 46 chromosomes each.
Which of the following statements is not correct?
Mitosis involves a series of two divisions.
Mitosis has one division of the chromosomes (and usually one cell division too). Meiosis is the special form of cell division for sperm and egg cells that has two divisions.
Which of the following is the main difference between mitosis and cytokinesis?
Mitosis is division of the nucleus, and cytokinesis is the division of the cytoplasm.
During which phase of mitosis do the chromosomes separate?
Anaphase
What role do the spindle fibers play in mitosis?
They attach to each chromosome to direct their movement
What process ultimately pinches a dividing cell to produce two daughter cells?
Cytokinesis
Which of the following statements is not correct?
Mitosis involves a series of two divisions
Which of the following best describes the end result of the semi-conservative nature of DNA replication?
Each strand has one old strand and one new strand.
Which of the following is not associated with DNA replication?
RNA
