30 Questions
During which phase of mitosis do spindle fibers start to form between the chromosomes?
Prophase
What happens to the centromeres during anaphase of mitosis?
They divide
What is the final step of mitosis before the cell returns to interphase?
Telophase
How many chromosomes do the daughter cells have after mitosis in humans?
46 chromosomes
Why does a cell need to divide according to the text?
To support its demands due to increased volume
What are the two main reasons mentioned for cells to divide?
Growth and Repair
During which phase of the cell cycle is the DNA copied?
Interphase
What happens during Prophase of mitosis according to the text?
Chromatids condense becoming visible
Why does a cell need to divide, as explained in the text?
To support its demands as volume increases faster than surface area
What is the main reason mentioned in the text for a cell to divide besides growth?
To repair or replace damaged cells
What happens to chromatids during Prophase of mitosis?
They become visible and condense
What is the function of centrioles mentioned in the text?
Make microtubules
When does a cell spend about 90% of its time in according to the text?
Interphase
What is formed during Mitosis according to the text?
Two complete identical sets of chromosomes
What is the main function of spindle fibers during mitosis?
Aid in pulling sister chromatids apart
What occurs during telophase of mitosis?
Nuclear membranes form around the new nuclei
How do daughter cells resulting from mitosis compare to the mother cell?
They are genetically identical
What is the significance of cytokinesis in the cell cycle?
To distribute cytoplasm equally between daughter cells
What happens to chromosomes during interphase?
They coil back into chromatin
Which phase of mitosis involves the alignment of chromosomes on the metaphase plate?
Metaphase
What is the outcome of mitosis in terms of cell numbers?
The number of cells remains the same
Why are identical daughter cells essential in the process of mitosis?
To maintain chromosome number and gene sequence
Why does a cell need to divide according to the text?
To repair or replace damaged cells
What happens to chromatids during Prophase of mitosis according to the text?
They condense and become visible
Which organelle appears and migrates to opposite sides during Prophase of mitosis?
Centrioles
What are the two main parts of a cell's life cycle mentioned in the text?
Interphase and mitotic phase
What is the primary function of spindle fibers during mitosis?
Assist in the alignment of chromosomes on the metaphase plate
Why are the daughter cells resulting from mitosis described as 'identical'?
They contain the same number of chromosomes as the mother cell
What happens to chromosomes as a cell transitions from telophase to interphase?
Chromosomes uncoil back into chromatin
Why is it crucial for each chromosome to have the same gene sequence in both daughter cells?
To maintain genetic identity between mother and daughter cells
