One of the major differences in the cell division of prokaryotic cells compared to eukaryotic cells is that
|
the chromosomes do not separate along a mitotic spindle in prokaryotic cells
|
|
|
A plant has 12 chromosomes at the end of mitosis. How many chromosomes would it have in the G2 phase of its next cell cycle
|
12
|
|
|
How many chromatids would this plant cell have in the G2 phase of its cell cycle
|
24
|
|
|
The longest part of the cell cycle is
|
interphase
|
|
|
In animal cells cytokinesis involves
|
the constriction of the contractile ring of microfilaments
|
|
|
Humans have 46 chromosomes. That number of chromosomes will be found in
|
the somatic cells
|
|
|
Sister chromatids
|
each have their own kinetochore
|
|
|
What is exhibited by cancer cells?
|
changing levels of MPF concentration
passage through the restriction point metastasis mitotic phase of the cell cycle |
|
|
The cell plate
|
forms at the site of the metaphase plate
fuses with the plasma membrane a cell wall is laid down between its membranes it forms during telophase in plant cells |
|
|
A cell that passes the restriction point in G1 will most likely
|
undergo chromosome duplication
|
|
|
In a plant cell, the centrosome functions in the formation of
|
microtubles of the spindle apparatus
|
|
|
What initiates the separation of sister chromatids in anaphase?
|
the cessation of delay signals received from unattached kinetochores
|
|
|
Cells growing in cell culture that divide and pile up on top of each other are lacking
|
anchorage dependence
|
|
|
Knowledge of the cell cycle control system will be most beneficial to the area of
|
cancer prevention and treatment
