Practise AP Biology 5.1.B questions by comparing the shared chromosome-separation machinery and different outcomes of mitosis and meiosis.
Both mitosis and meiosis are forms of cell division that produce daughter cells containing genetic information from the parent cell.
Describe TWO events that are common to both mitosis and meiosis that ensure the resulting daughter cells inherit the appropriate number of chromosomes.
Description (1 point each;
2 points maximum)
- Spindle elements (microtubules) form/attach to chromosomes
- Chromatin condenses
- Alignment of chromosomes across center of cell prior to chromosome separation
- Separation of chromatids/centromeres to daughter cells
- G2/M checkpoint occurs in both processes
- Replication or synthesis of DNA precedes mitosis/meiosis
- Cytokinesis separates daughter cells after mitosis/meiosis
