Meiosis Vs Meitosis1

paration. Normally is the separation not accomplished, but the homologous chromosomes stick together at certain points, the chaismata. This state is marked by the formation of cross-like structures, single or multipleloops. The diakinesis is the continuation of the diplotene. It is usually difficult to mark an exact limit between both states. The chromosomes condense and become more compact. The metaphase. From now on do the processes resemble that of mitosis again. The nuclear membrane is completely dissolved, the mitotic spindle fully developed. The homologous chromosomes do still stay together. The anaphase. During anaphase are the homologous chromosomes separated from each other. It is followed by the telophase, then by interkinesis. Shortly afterwards occurs the second mitotic division with the usual states of prophase, metaphase, anaphase and telophase. Here are the chromatids separated from each other.As a result of the meiosis of a diploid cell form four haploid cells, of which one or all can develop into gametes.Mitosis is the process that facilitates the equal partitioning of replicated chromosomes into two identical groups. Before the breakdown can occur, the chromosomes must become aligned so that the separation process can occur in an orderly fashion. The alignment of replicated chromosomes and their separation into two groups.Both the alignment and separation processes are the consequence of the chromosomes interacting with structures, known as microtubules. The microtubules become organized into an array known as a spindle, which forms early in mitosis, and then breaksdown as mitosis nears completion. Mitotic spindles are visible in living cells with the polarizing light microscope. Some of the spindle microtubules become attached to the chromosomes at sites known as kinetochores. They reside near the place on the chromosome known as its centromere, which can be observed with the light microscope. There are two kinet...
