ANSWERS (DETAILED ANSWERS) ALREADY
GRADED A+ 100% GUARANTEED TO PASS
CONCEPTS!!!
Cell Cycle - ....ANSWER ....✔✔ The life cycle of a cell
series of events in which a cell grows, prepares for
division, and divides to form two daughter cells
is controlled by both types of signal.
Apoptosis - ....ANSWER ....✔✔ is programmed cell
death
Decreases number of cells
Occurs during development to remove unwanted tissue
Tail of tadpole
Webbing between human fingers and toes
Plays important role in preventing cancer
Typical series of events brings about cell destruction.
Caspases are the enzymes responsible.

Held in check by inhibitors
Unleashed by internal or external signals
Somatic - ....ANSWER ....✔✔ cells are the body cells
that continue to undergo cell division even as an adult.
The stages of interphase - ....ANSWER ....✔✔ G1, S,
G2
Mitosis - ....ANSWER ....✔✔ division of the nucleus
the division of the nucleus, follows interphase.
The sister chromatids separate into daughter
chromosomes.
Distributed to two daughter nuclei
Cytokinesis - ....ANSWER ....✔✔ Two daughter cells
that are identical to the mother cell are the result.
the division of the cytoplasm, follows mitosis
Mitotic Stage - ....ANSWER ....✔✔ Cytokinesis
Mitosis
,3|Page
Eukaryotic cells - ....ANSWER ....✔✔ have a complex
system for regulating the cell cycle
Internal signals - ....ANSWER ....✔✔ ensure the stages
follow one another in the normal sequence.
They also check that each stage is properly completed
prior to the next stage.
External signals - ....ANSWER ....✔✔ tell the cell
whether on not to divide.
three checkpoint of the cell cycle - ....ANSWER ....✔✔
G1 - stops if DNA is damaged
G2 - stops if DNA did not finish replicating
M - stops if chromosomes are not going to be properly
distributed
Why are checkpoints are so important to the cell cycle?
- ....ANSWER ....✔✔ Checkpoints are critical for
preventing cancer development.
A damaged cell should not complete mitosis.
, 4|Page
G1 and G2 - ....ANSWER ....✔✔ Cell cycle
checkpoint. If DNA is damaged, apoptosis will occur.
Otherwise, the cell is committed to divide if growth
signals are
present and nutrients are available.
G2 - ....ANSWER ....✔✔ growth and final
preparations for division
Mitosis checkpoint. Mitosis will occur if DNA has
replicated properly. Apoptosis will occur if DNA is
damaged and cannot be repaired
M - ....ANSWER ....✔✔ checkpoint Spindle assembly
checkpoint. Mitosis will not continue if chromosomes are
not properly aligned
S - ....ANSWER ....✔✔ growth and DNA replication
Control of the Cell Cycle and Cancer - ....ANSWER
....✔✔ Mammalian cells enter the cell cycle only when
stimulated by an external factor.
Growth factors are signals that set into motion the events
associated with entering the cell cycle.
