Q. Which stage of the mitotic cell cycle can be thought of in some ways as the opposite of prophase?
Q. A cell has 5 chromosomes in G1. How many chromosomes will the cell have after it has finished mitosis but before cytokinesis?
Q. S phase is
a special "resting" phase
the phase of the cell cycle where DNA replication occurs
the phase of the cell cycle where two identical daughter cells are created
a part of interphase
both (B) and (D)
Q. The microtubule organizing center of the mitotic spindle is called the
Q. Which the following best describes the idea of a cell cycle checkpoint?
A domino-like series of events, with each event requiring completion by the previous event
A point that happens between G1 phase and S phase
A point where the cell must stop progression through the cell cycle until conditions are right for progression into the next stage
A point in the cell cycle between G2 and M phase
A point in the cell cycle between S and G2 phase
Q. Cancer is
a part of interphase
a disease that causes the cell to arrest in the cell cycle
a disease where the cell doesn't have any cyclins
a disease caused when a cell in the body acquires a genetic change that gives it a selective advantage for growth and reproduction over other cells in the body
the name of the checkpoint that occurs between S phase and G1 phase
Q. Which of the following aspects of mitosis are good examples of important structures/structural changes that ensure accurate chromosome segregation in human cells?
Formation of the mitotic spindle
Condensation of the chromosomes
Attachment of spindle to a chromosome's centromere
Breakdown of the nuclear envelope
All of the above
Q. In which of the following ways are mitosis and meiosis the same?
DNA is replicated before all cell divisions.
They both carry out recombination during telophase.
They both align their chromosomes in the center of the cell.
Homologous chromosomes are paired in both.
Sister chromatids are not paired in either mitosis or meiosis.
Q. In what stage of the cell cycle do chromosomes become rod-like structures and does the nuclear envelope break down?
A part of interphase
Q. If a G1 cell is fused to a cell in S phase, what will happen?
In both nuclei, DNA replication will cease.
Some signaling protein in the G1 phase cell will trigger S phase in the G1 cell.
Some signaling protein in the S phase cell will trigger S phase in the G1 cell.
Nothing will happen. The S phase nucleus will stay in S phase, and the G1 nucleus will stay in G1.
The nuclear envelope will break down in the G1 nucleus.
