What step of meiosis is mitosis most closely related to?
All steps of meiosis II are similar to the steps of Mitosis
Why are meiosis and mitosis confused?
Meiosis and mitosis are confused because iof the similarities in both the types of division.The similarities between mitosis and meiosis is that in both types of cell division -the cells divide to form daughter cellsDNA is replicated to form an extra setcentrioles move to the opposite end of the cell and form spindle fibers between themthe cell membrane, nucleolus and nuclear envelope all all break downthe chromosomes line up in the center of the cell and each spindle fiber is attached to the center of the chromosome by their centromerethe spindle fibres bring the chromatids to the opposite end of the cellin the ending phases of mitosis and meiosis the nuclear envelopes each contain half the amount of chromosomeboth the processes are a type of reproduction
Can human cells perform mitosis?
all cells perform mitosis, except sex cells which perform meiosis
Do pigs use meiosis or mitosis?
Many organisms use mitosis and meiosis. Namely, all eukaryotes probably use mitosis and meiosis. Only bacteria (prokaryotes) would not divide by mitosis and have no mechanism for meiosis as their chromosomes differ from those of eukaryotes.But eukaryotes all have the capacity for mitosis and meiosis. Eukaryotes include all animals, plants, protists and fungi.Thus, since pigs are animals (and are thus eukaryotes), then indeed they have cells that divide by mitosis and meiosis. Their body cells (somatic cells) divide by mitosis (for growth and repair). Their gametes (sperm cells and ova) are produced by meiosis as these cells must be divided to a haploid form before copulation and fertilisation. Two haploid gametes would fuse (fertilisation) to restore the resulting cell (zygote) to a diploid form. The zygote grows into a new piglet via mitosis.
Does mitosis or meiosis occur in all body tissue's?
Mitosis does not in fact occur in all of the tissues of the body. Mitosis occurs in all tissues of the body that are not sex tissues.
Mitosis is a division of what?
All the cells that divide in your body, except for sex cells, which divide through meiosis, divide by mitosis.
Is cell division the same in all cells?
No., its different but it also have a comparison, in mitosis it is one cycle, but in meiosis it repeats, the first cycle is what we called mitosis while if it repeats this is what we called meiosis,
Is crossing over unique to meiosis?
Yes. Crossover only occurs in prophase of meiosis I. Becuase it does not occur in mitosis, all the cells in our body are supposed to have the same genetic information (of course, excluding the cases where somatic mutations occur, such as in cancer).
Which meiotic division is most like mitosis?
There are many similarities between meiosis and mitosis, and the phases are almost identical. The main difference between them is that there are two divisions in meiosis, and the chromosomes are not replicated in both of these.
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 process occurs in the first of meiosis but is absent in mitosis?
There are many differences between meiosis and mitosis, and it can all be summed up by understanding they have different functions in life processes. Mitosis is all about creating cells that are identical to each other asexually. This provides multi-cellularity in multicellular beings. Meiosis, on the other hand, is all about the production of gametes (sex cells) from a single germ cell in order to make sexual reproduction possible. Taking all of this into considering, Mitosis is seen as being a part of a cyclical cell life cycle, so it happens more than once. Meiosis is a process that happens only once for a germ cell largely because it is a process that creates haploid cells from diploid cells. Note that because of these differences Mitosis requires the replication of DNA to occur in order for diploid cells to create more diploid cells. Diploid meaning that a full set of chromosomes are present; human diploid cells would have 46 chromosomes, 23 from the mother and 23 from the father that are paired up with each other. Haploid, would mean 23 human chromosomes in total; with regards to Meiosis, the chromosomes would be a combination of the genes that an individual inherited from his or her parents. In Meiosis, which is divided into two parts, replication of DNA occurs before Meiosis I is carried out, but no replication occurs before proceeding to Meiosis II in order to achieve creating haploid cells.
What produces gametes in mitosis?
Gametes are produced through meiosis, not mitosis. Meiosis is the cell division process that specifically produces haploid cells such as gametes (egg and sperm cells) in organisms. Mitosis is a cell division process that produces identical diploid cells for growth and repair.
