Mitosis 1
Somatic cells
What are non-reproductive cells developed by mitosis?
When the sister chromatids are lined up in the middle of the cell.
What is metaphase?
Diversity in gene frequencies.
What is genetic variation?
What are the main differences between mitosis and meiosis?
1) cytokinesis (amount of splits)
2) crossing over
3) end ploidy (1n/2n)
The amount of cells produced by mitosis.
What is 2?
When the DNA begins to condense.
What is prophase?
What is crossing over?
Why would sexual reproduction be favorable?
When conditions are bad and more genetic variation would be helpful.
When a cell has one set of chromosomes.
What is haploid?
When the nuclear envelope begins to dissolve and the DNA begins to organize itself.
What is prometaphase?
Prophase II
When the chromosomes condense and the nuclear envelope breaks down.
Why would asexual reproduction be favorable?
When the environment is favorable and genetic variation is not necessary for survival.
How bacteria reproduce.
What is binary fission?
When the replicated DNA are pulled to opposite poles of the cell.
What is anaphase?
Metaphase I
When the sister chromatids line up in the center and crossing over occurs.
Can an organism exist in a haploid state?
Yes, many do.
The action of a cell splitting.
What is cytokinesis?
When nuclear envelopes are formed around the newly duplicated DNA on opposite sides of the cell.
What is telophase?
Telophase II
Where nuclear envelopes develop around each set of chromosome (4) which begin to decondense.
How does mitosis differ between plant and animal cells? Why is this?
The splitting of the cell wall by a phragmoplast (in most cases, one species does this differently).
