Meiosis and mitosis: the main differences

All living organisms are composed of cells that live their lives, share and grow.The fission process can occur in two completely opposite ways, which have the same steps of meiosis and mitosis.

to living organisms whose cells contain a nucleus mitosis peculiar.This advantageously animal, plants and fungi.In science, the method of division is called vegetative propagation.Meiosis is also a way of division, but its feature - halving the number of chromosomes.

will understand the difference between mitosis by meiosis.Each stage of the process is similar, but each of them characterized by features which are the main differences.

first stage - is the process of dividing.The process of mitosis involves the division of chromosomes.Each of these two new forms, which are distributed between the two cells appeared.Science has proven that the fate of the new cells can have an entirely different outcome.Thus, for example, they may be further divided, or the division of one cell will continue.Possible termination of the fission process simultaneously in two cells.

process of meiosis runs a little differently.It builds on the two divisions.The first is accompanied by a decrease in the number of chromosomes exactly twice.Diploid cell splits into two haploid.Each chromosome is characterized by the presence of two chromatids.The second division does not imply a decrease in the number of chromosomes.As a result of the second division four new cells are formed.Each cell is localized one chromosome and a chromatid.Meiosis and mitosis, despite their similarities, the differences are at the first stage.

second phase - conjugation.The first cell division during meiosis involves pooling of homologous chromosomes.The process of mitosis is different complete absence of any kind of mating.This is followed by the alignment of chromosomes.Mitosis is characterized by the presence of paired chromosomes, but their uniform distribution around the equator is not in pairs, and at separately.The process of meiosis involves a completely different effect.Here the alignment along the equator passes in pairs.Comparison

during mitosis and meiosis revealed that the differences appear not only in the fission process, but eventually.Mitosis becomes the basis for the formation of couples and diploid somatic cells.It should be noted that throughout the process saved hereditary factors.As a result, occurrence of meiosis, the two pairs formed haploid gametes character.As to the question of inheritance, it is not stored and eventually reversed.

However, the most important difference lies in the nature of the process of reproduction.Meiosis - the process of sexual reproduction, which usually takes place exclusively in the germ cells at the stage of ripening.Mitosis is the basis of asexual somatic cells.Besides, mitosis is the only way to recover the somatic cells.

addition, meiosis and mitosis are considerable differences in the nature of its mission.Meiosis is accompanied by the maintenance of a constant number of chromosomes and stimulate the emergence of new.They are composed of hereditary factors.Mitosis is based on the doubling of chromosomes.It passes through the longitudinal division.Next, the resulting chromosomes disperse the daughter cells.Initial information is transmitted in its entirety and does not change.It was founded in the process of mitosis based on the development of organisms consisting of many cells.It can be concluded that meiosis and mitosis, followed by at least one target and have a huge number of differences and opposites.
