BIO 204 Week 1 Assignment Mitosis Cell
Phases (2 Set)
This Tutorial contains 2 Set of Answers
Mitosis: Cell Phases
The phases of mitosis can be observed by staining cells of rapidly
growing tissue so the chromosomes can be seen. You have read about
each phase separately, but remember that mitosis is a continuous
process and that the phases (designated by human observers for your
convenience) really merge from one to the next.
Review the phases of mitosis in your text. Pay particular attention to
the photographs of real cells undergoing mitosis.
Complete the table with the following:

· For each phase, in 40–60 words, describe in your own words
(paraphrase) the major events that occur in the cell. What would you
expect the cell or nucleus to look like in each phase? Could you see
the chromosomes and the nuclear membrane? If you could see the
chromosomes, how would you expect them to be arranged?
· Provide a drawing that you create of what the cell would look like in
each phase (Suggestion – take pictures and upload the pictures and
imbed them here).
· Include your references and in-text citations. APA formatted
references should go at the end of this document and each response
should have an in-text citation.
