Total questions: 16
Worksheet time: 12mins
What occurs during the G1 phase?
The cell grows and prepares for DNA replication.
The cell synthesizes proteins for cell division.
The cell undergoes apoptosis.
The cell divides into two daughter cells.
What is the main event that takes place during the S phase?
Protein synthesis
Cell division
DNA replication
RNA transcription
How does the G2 phase differ from the G1 phase?
The G1 phase is when the cell divides, while the G2 phase is when the cell grows.
The G1 phase focuses on cell growth and preparation for DNA replication, while the G2 phase focuses on preparation for mitosis after DNA replication.
The G1 phase occurs after mitosis, while the G2 phase occurs before DNA replication.
The G1 phase is focused on DNA repair, while the G2 phase is focused on nutrient absorption.
What is the significance of interphase in the cell cycle?
Interphase is significant for the cell's metabolic waste disposal.
Interphase is when the cell undergoes apoptosis.
Interphase is significant because it prepares the cell for division by allowing growth, DNA replication, and organelle duplication.
Interphase is the stage where the cell divides into two daughter cells.
What does the M phase represent in the cell cycle?
The M phase is when DNA is replicated.
The M phase occurs during interphase.
The M phase represents cell division.
The M phase is responsible for protein synthesis.
What types of cells are continually dividing in the human body?
Stem cells, skin cells, blood cells, and gastrointestinal tract cells.
Nerve cells
Muscle cells
Bone cells
How do daughter cells compare to the original cell after mitosis?
Daughter cells are larger than the original cell.
Daughter cells contain half the number of chromosomes as the original cell.
Daughter cells are genetically identical to the original cell.
Daughter cells have different genetic material than the original cell.
Which molecules act as gatekeepers for each checkpoint of the cell cycle?
p53 gene
cyclins and cycline-dependent kinases
thyroid hormones
What is the purpose the the cell cycle checkpoints?
To repair damaged cells before they enter cell division.
To remove damaged cells from an organism.
How many cell cycle checkpoints are there?
1
2
3
4
When is apoptosis initiated?
When DNA damage is repaired.
When cells are removed from the cell cycle.
When DNA damage cannot be repaired.
Which one of these is characteristic of cancer cells?
They undergo apoptosis.
They do not respond to growth inhibitors
They respond to growth inhibitors.
Which is a function of cyclins?
Cyclins are carbohydrates that regulate DNA replication during the mitosis phase of the cell cycle.
Cyclins are glycoproteins that repair DNA in the beginning of cell cycle.
Cyclins are proteins that regulate when and how often a cell divides.
Cancer promoting substances are called:
Tumors
Carcinogens
Cyclins
Malignant
