Name That Phase
During this phase, chromosomes line up on the equatorial plane of the cell
Metaphase
The name of the mass of genetic material that is composed of DNA and histone proteins?
Chromosomes
The name of a cell containing 2 sets of chromosomes.
Diploid (2n)
Mitosis is a separate phenomenon from the cell cycle
False
M phase = Mitosis
The total number of cells at the end of mitosis.
Two daughter cells
Fracturing of nuclear envelope & disintegration of the nucleolus
Prophase
The name of the equatorial plane of the cell where sister chromatids align
Metaphase plate
The term that describes when sister chromatids are separated at the centromere in anaphase
Disjunction
The purposes of mitosis is to create genetic variation within daughter cells
False
(Heal & regenerate tissues)
The method of asexual reproduction for bacterial & archaea
Binary Fission
The centromere dissolves & the sister chromatids are pulled towards opposite poles of the cell
Anaphase
In plant cells, this structure forms from Golgi vesicles to separate the two daughter cells
Cell plate
All cells in the body contain two sets of chromosomes, except gametes, which are.....
Haploid (n)
The vast majority of a cell's life span is spend in interphase
True
List all 6 phases of M-phase (mitosis) in order
Prophase, Prometaphase, Metaphase, Anaphase, Telophase, Cytokinesis
Nuclear enveloped reform around both sets of relaxed daughter chromosomes
Telophase
Central region where sister chromatids are adhered together
Centromere
If the original cell had 46 chromosomes, this is the number of chromosomes in each daughter cell after mitosis.
46
Apoptosis is spontaneous cell death that occurs in an uncontrolled manner in response to genetic mutation
False
Apoptosis is programmed, controlled cell death that is part of a normal cell cycle
Name the role of tumor suppressor genes in terms of how they regulate the cell cycle
Tumor suppressor genes can STOP cell cycle progression & induce apoptosis
Sticky kinetochores form on the side of the centromere, where spindle fibers attach
Prometaphase
Two barrel-shaped organelles that direct assembly of microtubules into the mitotic spindle
Centrioles
The diploid number for human beings is _____, while the haploid number is ______
Diploid= 46
Haploid= 23
Proto-oncogenes are mutated genes that cause cancer by causing uncontrolled cell division
False
Proto-oncogenes are normal cell cycle regulators.
Oncogenes are mutated proto-oncogenes that cause uncontrolled cell division
How might a single cell might become multinucleated (has multiple nuclei), in terms of mitosis
The cell goes through all phases of mitosis except cytokinesis, so it doesn't divide into daughter cells
