Questions and Answers
What occurs during telophase in terms of chromosome behavior?
During telophase, the daughter chromosomes begin to decondense and the nuclear envelope starts to form around them.
Describe the primary function of cytokinesis in the cell cycle.
Cytokinesis is the process where the cytoplasm of the parent cell divides to form two daughter cells, completing cell division.
In meiosis, what happens during prophase I that is crucial for genetic variation?
During prophase I, homologous chromosomes undergo synapsis, aligning side by side, which allows for DNA exchange between nonsister chromatids.

Study Notes
Cell Cycle
- A repeating sequence of cellular phases, each has its own unique process or event
- Inorder to ensure cell cycle regulation, critical points called 'checkpoints' must also be identified.
Interphase
- includes two phases: G1 phase, S phase, G2 phase
G0 Phase
- Also known as the resting phase
- The phase of the cell cycle where a cell is neither dividing nor preparing to divide.
G1 Phase
- The cell grows by producing more organelles and increasing the volume of the cytoplasm
- The cell is active at the biochemical level.
- The cell is accumulating the building block of chromosomal DNA, associated proteins, and enough energy reserves for the replication of DNA in the next phase.
