What else can I help you with?
What would happen if cytokinesis occurred without mitosis explain?
The chromosomes would not have replicated, so the resulting daughter cells will not have the correct ploidy.
What would happen to the number of chromosomes in a cell if mitosis occurred but cytokinesis did not take place?
The number of chromosomes in the cell would remain the same. Mitosis involves the division of the nucleus to ensure that each daughter cell receives a full set of chromosomes. Cytokinesis, the division of the cytoplasm, is responsible for separating the two daughter cells. If cytokinesis does not occur, the cell would end up with two nuclei but still have the same number of chromosomes.
When do chromosome duplicate themselves during mitosis?
Chromosomes duplicate during the S phase of interphase, which occurs before mitosis. Each chromosome replicates to form two identical sister chromatids that are held together at the centromere. These sister chromatids are then separated and pulled to opposite poles of the cell during mitosis.
What event must occur outside the nucleus before mitosis can begin?
Before mitosis can happen, the chromosomes inside the nucleus must separate to form identical pairs. This sets the stage for each of the daughter cells to have a copy of the DNA to replicate the full sequence.
What will happen next if a cell undergone DNA replication and the number of chromosomes has doubled?
The cell will enter the next phase, which is cell division or mitosis. During this process, the replicated chromosomes will be separated into two daughter cells, ensuring that each cell receives an identical set of chromosomes. This ensures that the genetic material is equally distributed between the daughter cells.
What stage in mitosis does the chromosomes uncoil happen?
During the telophase phase, the chromosomes begin to uncoil. There are six phases with mitosis and telophase is number four.
What would happen if cytokinesis occurred without mitosis explain?
The chromosomes would not have replicated, so the resulting daughter cells will not have the correct ploidy.
If a parent cell with 4 chromosomes undergoes mitosis how many chromosomes with each of the two daughter cells have?
Four chromosomes: through a process called meiosis, where the chromosomes are duplicated and then split into two cells each containing the same number of chromosomes that the parent cell started out with.

What stage of mitosis are the chromosomes most tightly condensed?
During the metaphase stage of mitosis, the chromosomes are most tightly condensed. This allows for the accurate alignment of the chromosomes along the metaphase plate before they are separated into separate daughter cells during anaphase.
What must happen before meiosis or mitosis can take place?
The cell must undergo DNA replication to ensure that each daughter cell will receive a complete set of chromosomes during meiosis or mitosis. This step is crucial for the accurate distribution of genetic material to the daughter cells.
What will happen next if a cell undergone DNA replication and the number of chromosomes has doubled?
The cell will enter the next phase, which is cell division or mitosis. During this process, the replicated chromosomes will be separated into two daughter cells, ensuring that each cell receives an identical set of chromosomes. This ensures that the genetic material is equally distributed between the daughter cells.
What is the difference between prophase mitosis and prophase meiosis?
In prophase I of meiosis, crossing over of homologous chromosomes occurs. This does not happen in prophase of mitosis.
What will happen to an unfertilized egg that undergoes mitosis but not cytokinesis?
Mitosis will separate the sister-chromatids of each chromosome, and each will now be called a chromosome (or daughter-chromosome).Without cytokinesis, the mother-cell will not split into two daughter-cells. The result will be a cell with twice as many chromosomes as the mother-cell.Since an unfertilized egg (ovum) is a gamete, it must be haploid. Doubling the number of chromosomes will produce a diploid cell.
What is the phase of mitosis when chromosomes become visibly shortened and thickened?
Prophase
