Mitosis and meiosis?
Meiosis is a form of cell division.
Let's talk about meiosis.
After meiosis 2 form 4 haploid cells.
Presentation on theme:"Meiosis and….
Then follows meiosis II, which is the same as mitosis.
In the gonads, ovaries andtestes occur both mitosis and meiosis.
This process occurs in two phases,meiosis I and meiosis II.
Meiosis I give to results cells with a halved number of chromosomes.
This can happen due to unequal crossover during meiosis.
Meiosis in the parents' gonads produce gamete cells which only contain 23 chromosomes each.
So in my project,it asks me to explain three differences between mitosis and meiosis.
In meiosis I is an exchange(crossing-over) between the father and the moderkromatiderna and become a mixture.
Cohesin is a protein complex that regulates the separation of sister chromatids during cell division,either mitosis or meiosis.
As meiosis is preceded by a duplication of DNA, chromosomes contain two chromatids with identical DNA content.
All cells share several similar characteristics of: Reproduction by cell division(binary fission,mitosis or meiosis).
Diploid organisms can, in turn, form haploid cells(gametes)that randomly contain one of each of the chromosome pairs, via meiosis.
Meiosis and Mitosis are just random acts of accidental attraction due to electronegativity and the charge within certain molecules?
Simple full trisomiya(non-hereditaryversion) is observed in 95% of patients,it is due to neraskhozhdeniem chromosomes during meiosis.
Tested for 29 genes that function in meiosis, they found 27 to be present,including 8 of 9 genes specific to meiosis in model eukaryotes.
Mutations are caused by radiation, viruses, transposons and mutagenic chemicals,as well as errors that occur during meiosis or DNA replication.
Importance of Meiosis Within a multicellular organism it is necessary that all cells(not to recognize each other as foreign) have the same hereditary heritage.
For example, the common intestinal parasite Giardia lamblia was once considered to be a descendant of a protist lineage that predated the emergence of meiosis and sex.
Meiosis also involves a stage of chromosomal crossover, in which regions of DNA are exchanged between matched types of chromosomes, to form a new pair of mixed chromosomes.
As part of the exercise, students are introduced to work on the microscope,studying various types of biological processes(mitosis, meiosis, etc.) and animal and plant parasites.
Trichomonas vaginalis, a parasitic protist, is not known to undergo meiosis, but when Malik et al. tested for 29 genes that function in meiosis, they found 27 to be present,including 8 of 9 genes specific to meiosis in model eukaryotes.
Alternation is observed in several rotifer species(cyclical parthenogenesis e.g. in Brachionus species) and a few types of insects, such as aphids which will,under certain conditions, produce eggs that have not gone through meiosis, thus cloning themselves.
