G1, S, G2
100
Koalas have 16 chromosomes. After a koala body cell undergoes mitosis, how many chromosomes should be in the daughter cells?
16
100
What are the places called during the cell cycle where a cell must stop before it can proceed to the next phase?
checkpoints
100
What is a stem cell?
A cell that has yet to decide what type of cell it will be. None of its genes are activated yet.
100
What is a conclusion that can be drawn from this graph?
Various answers
200
During which stage of interphase is DNA duplicated?
S or Synthesis phase
200
What are the building blocks of nucleic acids (DNA and RNA)
Nucleotides
200
Abnormally dividing cells that stay at the original site are called a:
benign tumor
200
What causes a stem cell to differentiated into a specialized cell?
Specific genes in the cell must be activated.
200
What type of reproduction is mitosis and how do all of the cells in a population compare to one another genetically as a result?
Asexual, all cells are identical
300
Put the stages in the correct order
D, A, F, C, E, B
300
The process of DNA copied into mRNA is called:
transcription
300
What would normally cause dividing cells to stop dividing?
When they are surrounded on all sides by other cells (contact inhibition)
300
What type of stem cell is being described:
These are limited to differentiating into the types of tissues in which they are found.
Found throughout the body
Replace worn out body cells.
Adult stem cells
300
Explain how liver and pancreas cells have the same DNA yet have different structures and functions.
different genes are activated in the two cell types
400
Name the stage of mitosis:
the nuclear membrane disappears, chromatic thickens into chromosomes, and spindle fibers start to form.
Prophase
400
What is this picture showing?
A plant cell doing cell plating/cytokinesis.
400
What type of tumor does someone have if the cells have metastasized?
malignant
400
What type of stem cell is being described?
Can become ANY type of cell.
Are found in the ball of cells formed the first week after fertilization. After then, they no longer exist in the organism.
Embryonic Stem cells
400
If a cell does mitosis but not cytokinesis, how many cells would there be at the end and how many nuclei would be in the cell(s)?
One cell with two nuclei
500
What is the phrase to help you remember the all of the phases of the cell cycle?
I Play Madden At The Crib
Interphase Prophase Metaphase Anaphase Telophase Cytokinesis
500
What structure in this image is responsible for reading the mRNA copied during transcription and transferring the appropriate amino acids?
tRNA
500
What would be checked at the G2 checkpoint?
Is the DNA completely replicated and are there any mutations?
500
Stem cells could help treat many injuries and diseases. Which type of stem cell are controversial to use/research on due to ethical reasons.
Embryonic
500
When a stem cell divides, what are the two possible options for what the daughter cells could be?
Either more stem cells or start differentiating into specialized cells
