Stages
What is Interphase?
The name of the net-like structure formed by the spindle fibers.
What is spindle apparatus or mitotic spindle?
The function of the spindle fibers?
What is they attach to the duplicate chromosomes to position them at the equatorial plate for metaphase and they pull apart the sister chromatids during anaphase?
Definition of sister chromatid.
What is two copies of chromosomes that connect?
Where spindle fibers connect on duplicated chromosomes.
What is kinetochores on the centromeres?
During this stage of mitosis, the connected sister chromatids are separated.
What is Anaphase?
The structure holding the two sister chromatids together.
What is centromere?
The function of mitosis.
What is for cells to reproduce and multiply?
Definition of centromere.
What is the place where two sister chromatids connect?
What is sister chromatids?
What is Telophase?
The name of the structure that forms in between a plant cell to separate its cytoplasm during cytokinesis.
What is cell plate?
Function of sister chromatids.
What is their pairing is essential for appropriate distribution of chromosomes into the daughter cells upon cell division?
Definition of cytokinesis.
During metaphase chromosomes line up at the midline of the cell. Name the midline.
What is an equatorial plate?
During this stage of mitosis, the spindle apparatus (mitotic spindle) is almost fully formed.
What is Prometaphase?
The name of the structure that forms in between an animal cell to separate its cytoplasm during cytokinesis.
What is cleavage furrow?
Function of centromere.
What is that directs the assembly of microtubule binding and serving as the cohesion sight between sister chromatids?
Definition of prophase.
What is nuclear membrane starts to disappear, DNA condenses?
If a cell originally contains ten chromosomes, how many chromosomes should it have during telophase and why?
What is twenty chromosomes during telophase because ten need to be found in each daughter cell after cytokinesis in order for the daughter cells to have the same number of chromosomes as a parent cell?
During this stage of mitosis, a photograph can be taken of the chromosomes to produce a karyotype chart.
What is Metaphase?
Some structures are involved in animal cell mitosis, but are not involved in plant cell mitosis. Name two of these structures.
What is centrioles and cleavage furrow?
Function of kinetochore.
What is mediate direct attachments between microtubules and centromeric DNA?
Definition of metaphase.
What is when centrioles attach to centromere and DNA lines up in the middle.
If an unequal number of chromosomes are found at the end of cell division, then there was an error in mitosis. Which stage of mitosis most likely went wrong and why?
What is during anaphase, an error occurred that prevented the proper separation of the sister chromatids. This resulted in the improper sorting of the chromosomes into daughter cells.
