Cytoskeleton
These are the smallest cytoskeletal proteins
actin filaments (microfilaments)
This protein must bind to a kinase in order for a cell to pass through cell cycle checkpoints.
Cylcin
What is the end product of mitosis?
2 genetically identical diploid daughter cells
What is the end product of meiosis?
4 genetically unique haploid gametes
Name the first song in The Lion King.
Circle of Life
Circular flow of cytoplasm in plant cells driven by actin-protein interactions
cytoplasmic streaming
Name the 3 cell cycle checkpoints.
G1, G2, M
When is DNA replicated during the cell cycle?
S phase
When are homologous chromosomes paired up? when are they separated?
prophase I, anaphase I
Which Disney movie includes the song "You'll be in my heart"?
Tarzan
These cytoskeleton components are more permanent than the others.
intermediate filaments
An example of a negative external signal that would prevent a cell from dividing.
Density-dependent inhibition
Put the stages of the cell cycle in order.
G1, S, G2, Prophase, prometaphase, metaphase, anaphase, telophase, cytokinesis
same genes, same order, different alleles
Which DIsney movie song contains this line "Wherever I wander, wherever I roam, I couldn't be fonder of my big home"?
The Bare Necessities (Jungle BOok)
These cytoskeletal components are required for movement of amoeba across a surface
actin filaments
How do cancer cells respond to regulatory signals?
Trick question, they don't!
When do sister chromatids "show up" in the cell cycle?
After S phase thru metaphase
What are the 3 events in meiosis that add genetic diversity?
crossing over between homologous chromosome pairs, independent assortment of chromosomes into gametes, random fertilization
Which Disney movie song has made the most money?
A 9+2 arrangement of microtubules makes up this cellular structure.
eukaryotic flagella and motile cilia
Which stage of the cell cycle do most chemotherapy drugs cancer treatments) target?
S phase
What would happen if microtubules disassemble too early in the cell cycle?
Sister chromatids would not be separated properly resulting in chromosome abnormalities in the daughter cells.
How is meiosis II similar to mitosis? How are they different?
Both separate sister chromatids
mitosis=diploid cells, meiosis II=haploid cells
Which character sings "Beauty and the Beast" in Beauty and the Beast?
Mrs. Potts
