What is happening in the image?
Mitosis
DNA replication
Metaphase
Cytokinesis
In which phase does this occur?
Mitosis
S Phase
Metaphase
Anaphase
In which phase/s does the cell divide into two identical daughter cells?
Interphase
S Phase
Metaphase and Anaphase
Mitosis and Cytokinesis
In an organism's infant stages, how is mitosis primarily helpful?
it makes the cells much larger so the organism is larger
it replaces damaged cells with new cells
it allows for specific tissues and organs to grow and develop
it replaces old cells with new cells
What is the base pair rule for DNA?
A-T
C-G
A-G
T-C
G-T
C-A
It varies with each individual

52
13
no way to tell
26
in which stage of the cell cycle will the DNA make a copy of itself?
M
S

What is cancer?
C. A type of viral infection
B. Uncontrolled growth of abnormal cells in the body
D. A condition caused by lack of sleep
A. A term for a large group of diseases caused by bacteria
DNA is the complete set of genetic instructions for an organism. How are the instructions determined?
by the sequence (order) of the base pairs
by how many of each base pair there are
by the size of the base pairs
by the percentage of the base pairs
Where in the cell does DNA replication occur?
ribosomes
cell membrane
nucleus
cytoplasm

The diagram below represents the cell cycle. When cells leave the cell cycle, they exit during G phase and then enter G phase, a resting 1 0 period. Most normal cells can leave G phase and reenter the cell cycle at G phase before 0 1 entering S phase. Cancer cells are different because they cannot enter G phase and are likely 0 to do which of the following?
Fail to complete S phase
Mutate during G phase
Repeat the cell cycle continuously
Die after completing mitosis
