When does nucleolus disappear in mitosis
A naphase During telophase , two distinct nuclear membranes develop encompassing the two identical sets of chromosomes. At the same time, the cytoplasm divides between the two new cells, and the cell membrane begins to pinch off the cell contents into two daughter cells. T elophase Finally, the new identical cells separate and once again enter interphase in preparation for a later mitotic division. While the chromosomes are no longer visible, they will be replicated just before mitosis begins.

Hanley Rd, Suite St. Louis, MO We are open Saturday and Sunday! Subject optional. Email address: Your name:. Possible Answers: Anaphase. Correct answer: Anaphase. Explanation : The phases of mitosis can be described as follows: During prophase chromatin condenses to form discrete chromosomes. During metaphase microtubules attach to the kinetochores and chromatids begin segregating.
During anaphase sister chromatids have been separated and reside at opposite poles of the cell. Cytokinesis the dividing of the cytoplasm into two cells follows telophase. If the cell were arrested during telophase, distinct chromatids would no longer be visible. Report an Error. Possible Answers: Anaphase, metaphase, prophase, telophase.
Correct answer: Prophase, metaphase, anaphase, telophase. Explanation : Mitosis is the process of cell division, and is separated into four stages. Which of the following events does not take place in prophase? Possible Answers: Sister chromatids are separated. Centrioles move to the opposite ends of the cell. Correct answer: Sister chromatids are separated. Explanation : Prophase is the first stage of mitosis, during which the cell begins to position itself in order to separate the chromatids and divide.
Chromatid separation is not seen until anaphase. Possible Answers: Prophase, metaphase, anaphase, telophase, cytokinesis. Prophase, interphase, metaphase, anaphase, telophase. Anaphase, prophase, metaphase, telophase, interphase. Anaphase, cytokinesis, metaphase, prophase, telophase. Correct answer: Prophase, metaphase, anaphase, telophase, cytokinesis. Explanation : There are five main steps of mitosis. Prophase: the nuclear envelope breaks down, chromosomes condense, and spindle fibers connect to sister chromatids.
Metaphase: spindle fibers pull sister chromatids to the metaphase plate at the equator of the cell. Anaphase: spindle fibers separate sister chromatids to opposite poles of the cell. Cytokinesis: the cell cytoplasm splits completely in half where the cleavage formed, giving two identical daughter cells with the same chromosomes as the parent. In which phase of mitosis do chromosomes align at the center and spindle fibers become visible?
Possible Answers: Interphase. Correct answer: Metaphase. Explanation : Mitosis involves four distinct stages: prophase, metaphase, anaphase, and telophase. What is the correct sequence of the stages of the M phase of the cell cycle? Possible Answers: Telophase, anaphase, metaphase, prophase. Explanation : The mitosis M phase of the cell cycle has four sequential stages: prophase, metaphase, anaphase, and telophase.
The division of centromeres occurs during which phase of mitosis? Possible Answers: Telophase. Filip Ochoa De Alda Professional. Why is the nucleolus important? Because of its close relationship to the chromosomal matter of the cell and its important role in producing ribosomes, the nucleolus is thought to be the cause of a variety of different human diseases.
Koichi Veeraraju Professional. What is the purpose of meiosis? Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs.
Its goal is to make daughter cells with exactly half as many chromosomes as the starting cell. Clovis Javicoli Explainer. Is a nucleolus an organelle? The nucleolus , or plural nucleoli , is normally a circular structure composed of proteins and nucleic acids. Nucleoli are not typical organelles for the reason that they have no lipid membrane, making it with of the few non-membrane bound organelles in the cell. Urias Muzhdabaev Explainer. What does nucleolus contain?
The nucleolus is a round body located inside the nucleus of a eukaryotic cell. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes.
Nathaniel Awduewski Explainer. What is the purpose of mitosis? Mitosis is a process where a single cell divides into two identical daughter cells cell division.
During mitosis one cell? The major purpose of mitosis is for growth and to replace worn out cells. Eberhard Berezinsky Pundit. How is nucleolus formed? It appears as an electron-dense area under electronic microscope observations. Clarisa Ding Pundit. Why is the nucleolus darker than the nucleus? I heard that the reason why nucleolus in the nucleus looks darkest dense is that there are many ribosomes.
Since there are so many ribosomes needed in the cell, this little "factory" is very busy, and there are a great number of molecules in a relatively small region. This makes it look very dense, because it is! Kaleigh Gomez De Salazar Pundit. At what stage does the spindle appear? Oma [email protected] Pundit. What structure holds chromatids together? The centromere is the point of attachment of the kinetochore, a structure to which the microtubules of the mitotic spindle become anchored.
