Phases
What are the phases of mitosis in order?
What is prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis
Between mitosis and meiosis, which has more stages?
meiosis
What is: proteins attached to the centromere that link each sister chromatid to the mitotic spindle?
Kinetochore
What is the name of the process that controls cell division and ensures cells divide only when needed?
what is cell regulation
Mitosis helps your body grow using
what are cells
In which phase do spindle fibers start to appear?
What is prophase?
True or false: Mitosis happens in somatic cells. Meiosis happens in reproductive/germ cells
what happens to the microtubules during Anaphase? What is its function?
Microtubules shorten and pull chromosomes apart
What group of proteins help regulate the cell cycle by activating cyclin-dependent kinases (CDKs)?
what is cell cycle regulation?
The disease that can result when cell division becomes uncontrolled
What is cancer?
What is the final stage of mitosis?
What is cytokinesis?
True or false: after mitosis the cells have more genetic diversity
False
What are the key components of the mitotic spindle and how do they interact with chromosomes during mitosis?
Microtubules by extending during prometaphase and shorten during anaphase.
what are checkpoints?
The type of reproduction mitosis allows organisms to create genetically identical offspring
What is asexual reproduction?
What phase of mitosis involves separation of sister chromatids to opposite poles?
What is anaphase?
How many cell divisions does meiosis have
2
How does the cell ensure that all chromosomes are properly aligned at metaphase before anaphase begins?
The cell’s “spindle checkpoint” which makes sure that the microtubules are attached to the kinetochores of each chromosome.
What is the G2 checkpoint?
Checks for completion of DNA replication and DNA damage
The programmed death of damaged cells is called
what is apoptosis
Which phase of mitosis have the chromosomes align in the center of the cell?
What is metaphase?
How many daughter cells does mitosis end with
two diploids
If a chromosome is duplicated is it one or two chromosomes? How many sister chromatids?
1 chromosome, 2 sister chromatids
What does contact inhibition initiate?
initiates signal transduction pathway that stops the cell cycle in the g1 phase
Abnormal cells that are not considered cancerous and do not spread through the body are?
what is benign tumor
