Cell Numbers
There are 20 chromatids in a cell, so there are this many centromeres.
What is 20?
Chromosomes are made up of this and DNA.
What are Proteins?
This would happen is a cell did go through mitosis but not cytokinesis.
This is where the microtubules of the spindle fibers originate.
What is centrosome?
The first checkpoint in the cell cycle where a cell will be caused to exit the cycle if this point is not passed.
What is G1?
Compared to Prokaryotes, Eukaryotes genetic material could be considered this?
What is to have more DNA molecules and a lager genome?
This is the definition of the cleavage furrow?
What is a groove in the plasma membrane between daughter nuclei?
Movement of the chromosomes during anaphase would be most affected by a drug that prevents this.
What is shortening of microtubules?
Motor proteins require this to function in the movement of chromosomes toward the poles of the mitotic spindle
What is ATP?
The protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex.
What is cyclin?
When there are 20 centromeres in a cell at anaphase, there will be this many chromosomes in each daughter cell.
What is 10?
Besides the ability of some cancer cells to overproliferate, what else could logically result in a tumor, this also can happen.
What is lack of appropriate cell death?
This would be considered the beginning of anaphase.
What is cleaving of the chromatid cohesion by an enzyme?
Cells from advanced malignant tumors often have very abnormal chromosomes as well as an abnormal number of chromosomes because of this.
What is Cell cycle checkpoints are not in place to stop cells with chromosome abnormalities?
The protein maintained at constant levels throughout the cell cycle that requires cyclin to become catalytically active
What is Cdk? (Kinases)
a chemotherapeutic drug is useful for treating cancer cells, because it does this?
What is it interferes with rapidly dividing cells?
This most accurately describes a cyclin.
What is it activates a Cdk molecule when it is in sufficient concentration?
A cell is in late anaphase of mitosis, which will allow this to be seen.
What is a clear area in the center of the cell?
When they stop dividing, they do so at random points in the cell cycle; they are not subject to cell cycle controls; and they do not exhibit density-dependent inhibition when growing in culture.
What is cancer cells?
The triggers the cell's passage past the G2 checkpoint into mitosis.
What is MPF?
A particular cell has half as much DNA as some other cells in a mitotically active tissue. The cell in question is most likely in this phase.
What is G1?
Through a microscope, you can see a cell plate beginning to develop across the middle of a cell and nuclei forming on either side of the cell plate. This cell is most likely going through this.
What is a plant cell in the process of cytokinesis?
The cell cycle checkpoints are all similar in this way.
What is they give the go-ahead signal to progress to the next checkpoint?
This does not occur in mitosis.
What is replication of DNA?
As cells become more numerous, the cell surface proteins of one cell contact the adjoining cells and they stop dividing.
What is density-dependent inhibition?
