What happens to the DNA during Prophase 1 of mitosis?
DNA coils tightly, resulting in shortened and thickened chromosomes.
What is the role of microtubules in Prophase 1?
Microtubules organize into a spindle.
What occurs to the nuclear membrane during Prophase 1?
The nuclear membrane breaks down.
What is a key feature of Metaphase 1?
Chromosomes attach to the spindle at their centromeres and align along the cell.
What happens to the centromeres during Anaphase 1?
Centromeres divide, releasing tension and allowing chromatids to separate.
During Anaphase 1, what occurs to the cell's chromosomes?
Chromatids separate and become independent chromosomes, moving to opposite ends of the cell.
What is the shape of the cell during Telophase 1?
The cell resembles a dumbbell with a set of chromosomes at each end.
What happens to the spindle during Telophase 1?
The spindle falls apart.
What is the purpose of Cytokinesis following mitosis?
Cytoplasmic division occurs to distribute organelles and macromolecules between two daughter cells.
What mechanism helps separate the two cells during Cytokinesis?
Microfilament band contracts to separate the two cells.
