Term | Definition |
---|---|
What is the cell cycle? | The process by which cells divide |
What are the main phases of the cell cycle? | Interphase and mitosis |
During which phase of the cell cycle does DNA replication occur? | S Phase |
Which checkpoint ensures that DNA replication has been completed accurately before cell division proceeds? | G1/S checkpoint |
What is the correct order of the stages of mitosis? | Prophase, metaphase, anaphase, telophase |
Which phase of the cell cycle is characterized by cell growth and normal metabolic processes? | G1 Phase |
What is cytokinesis? | Division of the cytoplasm |
What is the role of cyclins and cyclin-dependent kinases (CDKs) in the cell cycle? | They regulate progression through the cell cycle |
Which phase immediately follows mitosis in the cell cycle? | Cytokinesis |
What is the significance of the G1 checkpoint? | It checks for DNA damage before replication |
What is the name for the "in between" phase in cell divisions? | interphase |
In interphase, the DNA is in the form of loose threads called? | chromatin |
During prophase, DNA condenses into x-shaped structures called? | chromosomes |
During metaphase the chromosomes line up along the ????? of the cell. | middle |
During what stage do the chromosomes pull apart? | Anaphase |
The cytoplasm splits into two daughter cell during this process? | cytokinesis |
What structure reappears during telophase? | The nucleolus membrane |
During which stage does the DNA copy itself? | S phase |
The spindle attaches to what structures? | centrioles |
During what phase does the spindle form? | Prophase |
