When is the only time when chromosomes are visible?
You can see a chromosone at all times, however they are most easily visible during mitosis, when the cell is dividing. During this process the chromosomes condense, making them more easily visible.
Process occurs the same number of times in both mitosis and meiosis?
No. Mitosis , process of nuclear division in a living cell by which the carriers of hereditary information, or the chromosomes, are exactly replicated and the two copies distributed to identical daughter nuclei.In Meiosis, the cells that are formed have 1/2 the number of chromosomes and the cells are called gametes. They are not identical to the original cell.
How many times does the parent cell divides in mitosis?
Once, and then the two daughter cells can grow and later divide.
When does mitosis happen?
Mitosis is the process of separating chromosomes in its cell nucleus into two identical sets in two nuclei within eukaryotic cells. As for when it takes place, I believe it starts after the G2(second gap) stage of Interphase ends.
What are similarities and differences of mitosis and meiosis?
Mitosis vs. MeiosisBoth mitosis and meiosis are mechanisms that describe cell division. The difference is particularly noticeable when one looks at the DNA in the cell's nucleus. After mitosis, each of the daughter cells will have exact same DNA strands, while after meiosis each daughter cell will only have half of the DNA strands. (Sometimes the division is not exactly half/half, but that is not important for this answer). Because meiosis only has half the information that the parent cell had, the cell is (as far as we know) unable to reproduce by itself. The reason for meiosis is for reproduction of a multi-cellular organism as well as genetic diversity due to crossing over. One daughter cell (from the male of the species) will try to find a compatible daughter cell (from the female of the species) and fertilize it. This then becomes and embryo and the specie has successfully reproduced. And this is how you, the reader, came into existence.Other characteristics:Parent cell - full set of chromosomes in both mitosis and meiosis (2n).Number of divisions - mitosis 1; meiosis 2.Chromosome number of daughter cells - mitosis full set (2n) and meiosis half set (n).Crossing over - mitosis no; meiosis yesPaired homologues - mitosis no; meiosis yesDNA of daughter cells - mitosis identical to parent; meiosis daughter cells differentNumber of DNA replications - mitosis 1; meiosis 2Number of daughter cells - mitosis 2; meiosis 4Type of cells - mitosis somatic; meiosis sex cells
What do the daughter cells that result from mitosis have?
it has four times the number of chromosomes as the parent cell.
The cell division process that only occurs in specific cells and at specific times is?
The cell division process that only occurs in specific cells and at specific times is called mitosis. Mitosis is a type of cell division that results in two daughter cells with the same number of chromosomes as the parent cell. It is essential for growth, repair, and maintenance of multicellular organisms.
When is the only time when chromosomes are visible?
You can see a chromosone at all times, however they are most easily visible during mitosis, when the cell is dividing. During this process the chromosomes condense, making them more easily visible.
What does the chromatin material get organised into during cell division?
During cell division, chromatin material gets organized into tightly packed structures called chromosomes. Chromosomes contain DNA that carries the genetic information of the cell, crucial for proper cell division and inheritance of genetic traits.
If a young plant has 128 cells how many times has it gone through the process of mitosis?
seven
How many times chromosomes replicate in meiosis?
They replicate before meiosis begins, as it is the division phase. The chromosomes duplicate during interphase which is right before the beginning of meiosis. After going through meiosis I the chromosomes DO NOT duplicate nor do they cross over they simply continue on. Hope this helps. :)

Meiosis divides the chromosomes in the nucleus how many times?
Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division)
When does mitosis happen?
Mitosis is the process of separating chromosomes in its cell nucleus into two identical sets in two nuclei within eukaryotic cells. As for when it takes place, I believe it starts after the G2(second gap) stage of Interphase ends.
What is the number of cells division in mitosis?
Mitosis involves one cell division and ends up with two daughter cells. Meiosis involves two cell divisions and ends up with four daughter cells.
Why does a gamete produced during meiosis have half as many chromosomes as a daughter cell produced during mitosis?
During meiosis, the cell undergoes two divisions resulting in four daughter cells each with half the number of chromosomes as the parent cell. This reduction is necessary for sexual reproduction to ensure the correct number of chromosomes is maintained when two gametes, each with half the chromosome number, combine during fertilization to form a diploid zygote. In contrast, mitosis is a single division process that results in two daughter cells with the same number of chromosomes as the parent cell, allowing for growth and repair in multicellular organisms.
