A chromatid is one of the two identical copies of DNA making up a chromosome.
TRUE
The structure shown in figure 9-1 is a duplicated chromosome.
TRUE
. A cell splits into two daughter cells during cytokinesis
TRUE
Typically, the longest phase of mitosis is metaphase.
FALSE
During Metaphase, the chromosomes gather in the middle.
TRUE
. After telophase is completed, the process of mitosis is completed.
TRUE
. Cancer is a disease caused by the severe disruption of the mechanisms that normally control the cell cycle.
TRUE

Prophase is a state of mitosis in which chromatin condenses into chromosomes.


TRUE
Most of the cells growth happens during the S phase of the cell cycle.
FALSE
A cell’s chromosomes are duplicated during interphase
TRUE
Reproduction by simple cell division is called sexual reproduction; wheras the process in which two parents contribute genetic material is called asexual reproduction.
FALSE
Cancer is a disease in which some cells lose the ability to control their ________________.

Prophase
During which phase do spindle fibers form?
prophase
A spindle forms in which phase?
prophase
During ______________, the nucleus and the duplicated chromosomes divide and are evenly distributed, forming two “daughter” nuclei.
Mitosis
. Which of the following is not a correct statement about the events of the cell cycle? A. the cell grows during G2 phase
B. DNA replicates during S phase
C. Cell division ends with Cytokinesis
D. Interphase is usually the longest phase




Answer; A
Together the G1 phase, the S phase, and the G2 phase are called __________________.
Interphase
What event occurs during interphase?

Cell division is completed when which step is finished:
Cytokinesis
. The structure labeled A in figure 9-3 is called the
cell plate
Look at figure 9-3. The process is called
Cytokinesis

Which of the following is a phase of mitosis?
Prophase
One difference between cytokinesis is that plant cells have a _________________.
Cell plate
first phase of mitosis is called?
Prophase
What is a malignant tumor?
a mass of cancer cells
During which phase of mitosis do the chromosomes line up along the middle of the dividing cell?
Metaphase
During metaphase each chromosome is connected to a ________________________.
spindle fiber
Which of the following is NOT part of mitosis?A. prophase B. metaphase C. telophase D. interphase
Answer: D
The order of phases during mitosis:

In the disease _________________, the mechanisms that normally control the cell cycle are disrupted.
Cancer
