100
During these two phases of mitosis the nuclear envelope fragments, some microtubules attach to kinetochores, the centrosomes are at opposite poles of the cell, and the chromosomes line up in the middle of the cell.
What is prometaphase and metaphase
100
In this cell phase, each of the 46 pairs of chromosomes are replicated.
What is S phase
100
Why normal cells stop dividing when they have formed a single layer.
What is density dependent inhibition?
100
Also called the "narrow waist" of a chromosome.
What is the centromere?
100
Exists in the nucleus in an uncondensed form when the cell is not dividing.
What is chromatin?
200
During this phase of mitosis, the chromosomes duplicate, the nuclear envelope and nuclei are still present, and the centrosomes duplicate.
What is interphase
200
This cellular phase occurs if a cell doesn't pass a cellular checkpoint, labeling it for destruction.
What is G0 phase
200
To divide, a cell must be attached to a sub-stratum.
What is anchorage dependence?
200
This structure consists of fibers made of microtubules and associated proteins.
What is a mitotic spindle?
200
Joined copies of the original chromosome.
What are sister chromatids?
300
During this phase of mitosis the chromosomes split into sister chromatids and each of the two poles have equal and equivalent collections of chromosomes.
What is anaphase
300
Cellular content, excluding the chromosomes, are replicated during this cellular phase.
What is G1 phase
300
These abnormal cells continue to grow by overlapping each other because they lack density dependent inhibition.
What are cancer cells?
300
A subcellular region containing material that functions throughout the cell cycle to organize the cell's microtubules.
What is the centrosome?
300
A cellular structure carrying genetic material, found in the nucleus of eukaryotic cells.
What is a chromosome?
400
During these two phases of mitosis, the nuclear envelope and nuclei reappear, chromosomes become less condensed, and the cleavage furrow pinches the cell in two.
What is telophase and cytokinesis
400
Early in this phase, the mitotic spindle begins to form, and at the end of this phase, the cell divides.
What is M phase
400
Cancer cells can grow anywhere because they don't need an anchor. This shows a lack of ___.
What is anchorage dependence?
400
A structure of proteins attached to the centromere that links each sister chromatid to the mitotic spindle.
What is the kinetochore?
400
A region containing specific DNA sequences where the chromatid is attached most closely to the sister chromatid.
What is the centromere?
500
During this phase of mitosis, chromosomes condense and are visible, the mitotic spindle begins to form, and centrosomes move away from each other.
What is prochase
500
During this phase, the centrosomes replicate.
What is G2 phase
500
This gorws from a single cancer cell and can be benign or malignant.
What is a tumor?
500
Located at the center of the centrosome.
What are centrioles?
500
Two of these are the product of mitosis.
What are daughter cells?
