Mitosis
What is the first stage of mitosis?
prophase
In what stage is DNA Replicated?
S phase
What step is this description refering to:
-the microtubules (spindles) of the mitotic spindle start moving towards the chromosomes
-microtubules grab the chromosomes by a protein complex on the centromere (kinetochores)
pro-metaphase
What type of gene is this?
R
dominant
what type of gene does a lowercase letter represent
recessive
In what stage does microtubules pulls the chromosomes apart, causing the sister chromatids separate to the opposite ends
anaphase
What are these genes called?
-onocone (cancer), Proto-oncogenes (normal), Tumor suppressors genes check
Bonus point: which check-point checks for these?
regulatory genes
bonus: m check-point
What comes after telophase 1?
prophase 2
What law/principle is this describing:
-individuals have two alleles for each trait, but only one is passed to each gamete (egg or sperm) during sexual reproduction.
Principle/law of Segregation
what is this describing:
a cell or organism with an abnormal number of chromosomes, meaning it has one or more extra or missing chromosomes.
aneuploid
What would occur if the cytokinesis process was inhibited in a cell that had just successfully completed telophase?
A cell with two nucleus
What protein will stop the cell cycle leading to apoptosis if there is something wrong?
protein p53
What does Meiosis yeild in the end?
4 unique hapolid daughter cells
Draw the punnet square for a mom with Rr and dad with rr.
Rr rr
Rr rr
how does cyclin binding to Cdks activate protiens?
through phosphorylation
During what stage is the creation/polymerization of actin filaments vital?
Cytokinesis
What molecule regulates the cell cycle but the amount of it varies throughout the cell cycle.
cyclin
Where does the microtubules (spindles) of the mitotic spindle grab onto the chromosomes?
kinetochores on the centromere
If I have a flower with purple and white petals what dominance is being displayed?
codominance
What degree of dominance is being presented if you have a white male dog breed with a brown female dog and you get a gray puppy as offspring?
Incomplete dominance
