Mitosis and meiosis both represent cell division that occur in humans and other animals.

Meiosis is the specialized cell division that generates gametes. In contrast to mitosis, molecular mechanisms and regulation of meiosis are much less understood. Meiosis shares mechanisms and regulation with mitosis in many aspects, but also has critical differences from mitosis. This review highlights these differences between meiosis and mitosis.

Similarities of Mitosis and Meiosis

Mitosis and meiosis share some similarities, but also some differences, most of which are observed during meiosis I. Mitosis and meiosis are both forms of division of the nucleus in eukaryotic cells. They share some similarities, but also exhibit distinct differences that lead to very different outcomes. The purpose of mitosis is cell regeneration, growth, and asexual reproduction,while the purpose of meiosis is the production of gametes for sexual reproduction. Mitosis is a single nuclear division that results in two nuclei that are usually partitioned into two new daughter cells.

Introduction In order for organisms to grow, cells have two options: they must either replicate themselves to create more cells, or the cells themselves must expand in volume. In humans, tissues such as the skin and blood contain cells that are actively dividing , whilst other tissues such as fat contain cells that expand good if you need energy for winter, bad if you are trying to fit into some expensive jeans. Other cells, such as neurons, will never divide again once they are terminally differentiated; they are post-mitotic. In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells?

Mitosis versus meiosis

Mitosis is a process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell. Meiosis is a type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells. Thank you but please tell briefly about both means in meiosis the chromosome number is half. I cannot understand this please explain. Thanks a lot!

General Education. Getting mitosis and meiosis confused on a biology exam can cost you a lot of points, so it's important to keep these two cellular processes straight. Mitosis and meiosis are both processes of cell division.

Mitosis has the diploid number of chromosomes and produces two identical daughter cells with 46 chromosomes , on the contrary in Meiosis four genetically distinct daughter cells with each having 23 chromosomes in the human cells are produced which have the haploid number of chromosomes. The above points are the critical one to distinguish between the two, though there are many more to focus, which will make the reader much clear about the terms Mitosis and Meiosis. Life starts from a single cell, which further divides and grow and start functioning for the task they have been assigned; with the purpose of growth and development of the body and to transfer the parental DNA to their offsprings.

26.2B: Comparing Meiosis and Mitosis

Cells divide and reproduce in two ways, mitosis and meiosis.

Между деревьев в левой части кадра что-то сверкнуло, и в то же мгновение Танкадо схватился за грудь и потерял равновесие. Камера, подрагивая, словно наехала на него, и кадр не сразу оказался в фокусе. А Смит тем временем безучастно продолжал свои комментарии: - Как вы видите, у Танкадо случился мгновенный сердечный приступ. Сьюзан стало дурно оттого, что она увидела.

 Да будет тебе, Мидж.  - Бринкерхофф посмотрел на нее осуждающе.

ГЛАВА 25 Городская больница закрылась для посетителей. Свет в бывшем гимнастическом зале выключили. Пьер Клушар спал глубоким сном и не видел склонившегося над ним человека. Игла похищенного у медсестры шприца блеснула в темноте и погрузилась в вену чуть выше запястья Клушара. Шприц был наполнен тридцатью кубиками моющего средства, взятого с тележки уборщицы.
