Cells that divide during mitosis (not gametes). All have 46 chromosomes in humans
What are somatic cells
A certain species has 28 chromosomes in each of its newly formed daughter cells. The parent cells during G1 had this many chromosomes.
What is 28
This phase concludes nuclear division.
What is telophase
If cells in the process of dividing are subjected to colchicine, a drug that interferes with the polymerization and depolymerization of microtubules, at which stage will mitosis FIRSTbe arrested (stopped)?
Prometaphase
Humans have this number of chromosomes in their body cells.
What is 46
Sometimes described as a "full set" of chromosomes. Also referred to as two sets of chromosomes.
What is Diploid
Chromatid pairs first form during S phase, however this phase marks the last time they are together.
What is metaphase. They are separated in anaphase.
Suppose a biologist can retrieve a duplicated chromosomes from a eukaryotic cell. It might consist of which of the following?
Two sister chromatids with identical DNA.
This abbreviation describes a class of enzymes that activate proteins which control the cell cycle through phosphorylation.
What are Cdk's
Forms during plant cell cytokinesis
What is a cell plate
Animal cells have these located in their centrosomes
What are centrioles
Certain types of cells, like nerve cells, are said to be "stuck" in this phase.
What is G0
During prophase the nucleoli disappears, chromosomes condense, centrosomes move away from each other, and this begins to form.
What is mitotic spindle
These can be produced to initiate cell division by binding to nearby receptors of healthy cells. 50 of them are known.
What are growth factors
During which phase of mitosis do the sister chromatids become chromosomes?
What is anaphase
Most cells only divide when they are attached to an external surface, such as the flat surface of a neighboring cell.
What is Anchorage dependence.
The centromere is a region in which
The central portion of a duplicated chromosome that contains the two kinetochores of both sister chromatids.
Lengthen during anaphase
What are nonkinetochore microtubules
Many cells stop dividing when surrounded by a large quantity of other cells.
What is density-dependent inhibition
Platelets release this in efforts to heal a wound.
What is PDGF
A cleavage furrow forms in animal cells due to these.
What are microfilaments (actin)
This triggers the cell's passage past the G2 checkpoint into mitosis.
What is MPF
At which phase are the centrosomes notlocated at opposite ends/poles of the cell?
Prophase geniuses
For anaphase to begin, which of the following must occur?
Cohesin proteins must be cleaved by seperase.
Which of the following is a protein synthesized at specific times during the cell cycle that associates with a kinase to form a catalytically active complex?
Cyclin
