Mitosis POGIL Test| Quizzes and
100% Correct Verified Solutions
How many chromatids are in each replicated chromosome? - Answer two
sister chromatids
How many replicated chromosomes are in the original cell during prophase? - Answer
four
How many single chromosomes are in each of the new cells in telophase? - Answer four
each
What is a chromosome and why is it important? - Answer A chromosome is made of DNA
wrapped around proteins and contains all the genetic information for an organism.
What might the new cells in telophase contain if replication of chromosomes did not
occur before cytokinesis? Would cells be viable? - Answer The new cells might only
contain only half the original number of chromosomes, or one cell might contain more
chromosomes than the other if replication did not occur before cytokinesis. They
would not be viable. They wouldn't have a complete set of DNA.
Why do you think the cell needs to make more DNA during the S(ynthesis) phase in
the cell cycle? - Answer The cell must copy the chromosome material so if there is
enough to make two new cells with the correct chromosome number.
, During what phase of the cell cycle do you think the chromosomes are replicated?
- Answer Synthesis
In which phase of mitosis do you see the spindle fibers forming? - Answer Prophase
At what phase of mitosis do the replicated chromosomes (sister chromatids) separate?
- Answer Anaphase
In which phase do you see that the spindle fibers have disappeared? - Answer Telophase
Suggest the purpose of the spindle fibers during mitosis. - Answer The spindle fibers
separate the replicated chromosomes and move each single chromosome to the
opposite sides of the cells.
Predict how binary fission in prokaryotic cells might be different from mitosis in
eukaryotic organisms. - Answer Less complicated than mitosis. Single chromosome
is copied and cell is pinches into two new cells, each with a single chromosome.
Describe what happens to the nuclear membrane after prophase. - Answer It
breaks down.
Explain why it is necessary that the nuclear membrane disintegrates during mitosis. -
Answer It must be temporarily removed for the chromosomes to be divided into
two cells.
At what point during mitosis has the nuclear membrane reformed? - Answer Telophase
What is actually dividing during cytokinesis? - Answer Cytoplasm
