12 Questions
During which stage of mitosis do the chromosomes align in the centre of the cell and attach to microtubules?
Metaphase
What is the purpose of mitosis in multicellular organisms?
to create new cells for growth and repair old cells
What happens to the nucleolus during prophase?
It disappears
What is the result of mitosis in unicellular organisms?
Two identical daughter cells
During which stage of mitosis do the chromatids separate and move to opposite ends of the cell?
Anaphase
What happens to the chromosomes after mitosis is complete?
They decondense
What is the main difference between mitosis and meiosis?
Mitosis produces two identical daughter cells, while meiosis produces four daughter cells with half the genetic material.
What happens during prophase of mitosis?
Chromosomes condense and the nucleolus disappears.
What is the purpose of mitosis in multicellular organisms, other than growth?
To repair old cells.
What is the result of crossing over during meiosis?
Genetic material is exchanged.
What is the final stage of mitosis?
Cytokinesis
What is the purpose of metaphase 1 in meiosis?
Chromosomes align in pairs in the centre of the cell.
Learn about the Prophase stage of cell division where DNA replication and chromosome condensation occur before mitosis. Understand how chromatids separate and move to opposite ends of the cell to ensure identical chromosomes in each daughter cell.
