Example Question #12 : Cell Division
In which stage of mitosis do sister chromatids line up along an imaginary line that divides the cell in half?
Metaphase
G2
Cytokinesis
Anaphase
S phase
Metaphase
Metaphase is characterized by the lining up of chromosomes along the "metaphase plate," an imaginary line that divides the cell in half. Following metaphase and during anaphase, the sister chromatids will separate and move towards the poles of the cell.
Example Question #11 : Mitosis
Mitosis and meiosis are similar and often incorrectly thought of as the same process. Which of these best explains their differences?
The terms mitosis and meiosis can be used interchangeably when explaining cell division.
Mitosis will generate 4 daughter cells with half the genetic material from the parent cell, while meiosis will generate two daughter cells with the same genetic material from the parent cell.
Mitosis does not generate any new cell while meiosis does.
Mitosis will generate two daughter cells with the same genetic material from the parent cell, while meiosis will generate 4 daughter cells with half the genetic material from the parent cell.
Meiosis only occurs in humans while mitosis occurs in every living organism.
Mitosis will generate two daughter cells with the same genetic material from the parent cell, while meiosis will generate 4 daughter cells with half the genetic material from the parent cell.
There are many ways that mitosis and meiosis differ, in this question we are primed to look at the differences in the end products of each type of cell division.
Mitosis creates two new cells that are identical to the parent cell (diploid). Meiosis creates 4 new cells with half the genetic information (haploid) in each cell, and the cells are nonidentical to the parent cell and to their sister cells.
Example Question #14 : Cell Division
Which stage of mitosis exhibits chromatids lining up on the equatorial plate?
Prophase
Telophase
Metaphase
Anaphase
Prometaphase
Metaphase
Prophase- spindles forming, chromosomes condense, and the nuclear membrane begins to break down
Prometaphase- microtubules grow
Metaphase- chromatids are lined up in the center of the cell on the equatorial plate
Anaphase- the two chromatids of the chromosome are pulled apart at the centromere
Telophase- new nuclear membranes form around each set of chromosomes, the spindles break down, and chromosomes decondense
Example Question #15 : Cell Division
Which stage of mitosis exhibits the two chromatids of the chromosome are pulled apart at the centromere?
Anaphase
Metaphase
Telophase
Prophase
Prometaphase
Anaphase

Example Question #16 : Cell Division

Anaphase
Prophase
Prometaphase
Prophase

Example Question #13 : Mitosis
List the stages of Mitosis.
Premetaphase, metaphase, anaphase, telophase, interphase, cytokinesis, prophase
Interphase, Metaphase, premetaphase, anaphase, cytokinesis, telophase, prophase
Prophase, premetaphase, interphase, anaphase, telophase, metaphase, cytokinesis
Interphase, prophase, telophase, premetaphase, cytokinesis, metaphase, anaphase
Interphase, prophase, premetaphase, metaphase, anaphase, telophase, cytokinesis.
Interphase, prophase, premetaphase, metaphase, anaphase, telophase, cytokinesis.
Interphase would be first as this is the part of the cycle cycle that the cell prepares to enter Mitosis. The key indicators of prophase are that the nuclear envelope is still intact and the chromosomes are beginning to pair up sister chromatids. The mitotic spindle is also beginning to form. Premetaphase, the next phase, is when the spindle has attached itself to the respective chromosomes and they begin to migrate to the center of the cell. In Metaphase the chromosomes have lined up on the mitotic plate and beginning to separate. In anaphase each sister chromatid moves to its respective side of the cell, as it is being pulled there by the mitotic spindle. The last phase of mitosis is telophase, which is indicated by the beginning of the cell splitting into two, called cytokinesis.
Example Question #14 : Mitosis
At which phase of mitosis are the chromosomes separated and move to each side of the cell?
Anaphase
Metaphase
Telophase
Prophase
Premetaphase
Anaphase
Anaphase is where the duplicated chromosomes split, disconnected at the centromere, and each sister chromatid is moved towards opposite sides of the cells.
Example Question #12 : Mitosis
Telophase is the next phase in mitosis. List two things that occur during this phase.
Chromosome sets are assembled at opposite ends of the cell and a nuclear envelope forms around the chromosomes.
Chromosomes are lined up in the middle of the cell and the nuclear envelope begins to form.
The spindles begin to develop and pull each set of chromosomes to opposite sides of the cell.
Chromosomes are lined up in the center of the cell and the mitotic spindle begins to pulls them towards either side of the cell.
The nuclear envelope begins to breakdown and the chromosomes begin to move to opposite sides of the cell.
Chromosome sets are assembled at opposite ends of the cell and a nuclear envelope forms around the chromosomes.
Important indications that the cell is in telophase are that the chromosomes have been moved towards the opposite sides of the cell. The nuclear envelope does begin to form around the new respective nucleus of each daughter cell and the cell itself begins the stages of cytokinesis, or this splitting of the cell into two daughter cells.
Example Question #11 : Understanding Stages Of Mitosis
What term refers to the cell splitting into two daughter cells?
Cytokinesis
Interphase
Fission
Telophase
Anaphase
Cytokinesis
Cytokinesis is the division of the cell into two respective daughter cells. Cytokinesis can start as early as anaphase and moves through with telophase. The most important thing in this part of the process is to make sure that there is one nucleus in each new cell being formed. A protein filament ring, called the contractile ring, causes the middle of the cell to shrink and pinch off to form the two separate daughter cells.
Example Question #241 : High School Biology
What are two major events that occur in prometaphase?
The spindle is only beginning to form and the chromosomes are lined up on the metaphase plate.
The nuclear envelope is still intact and the chromosomes become condensed.
The nuclear envelope breaks apart, the mitotic spindle reaches the chromosomes.
Chromosomes become condensed and the nuclear envelope breaks down.
The nuclear envelope breaks apart, the mitotic spindle reaches the chromosomes.
During premetaphase the nuclear envelop has broken down and this allows the spindle, or the microtubules, begin to attach to the chromosomes at the kinetochore. The microtubules begin to put force on the chromosomes to begin moving them to the middle of the cell.
