Mitosis and Meiosis

MITOSIS Occurs in somatic cellular phones. Consists of only one thermonuclear division. Cytokinesis takes make out out only once. Involves division of chromosomes. Dividing cells can be monoploid or diploid. Does not involve either pairing of homological chromosomes or crossing over. Two girl cells atomic design 18 skeletal systemed. Number of chromosomes present in the bring forth cell is maintained in both the daughter cells. indeed it is an equational division. Original characters of the chromosomes ar maintained in the daughter cells. little girl cells ar confusable to for each one opposite and also to the fender mother cell. Helps in growth and body repairs. MEIOSIS Occurs in reproductive cells. Consists of cardinal nuclear divisions M-I and M-II. May take carry only once (simultaneous type) or twice (successive type). Involves separation of homologous chromosomes in M-I and division of chromosomes in M-II. Dividing cells are diploid. Pairing of homolog ous chromosomes and crossing over occur during Prophase-I. Four daughter cells are formed. Diploid number of chromosomes is reduced to haploid in each daughter cell. Therefore it is a reduction division. Chromosomal characters are altered payable to crossing over causing recombination of genes. miss cells differ from each other as well as from the original mother cell. Helps in the sexual reproduction and prescript of chromosome number in the deportment cycle of sexually reproducing being

--References ! --> Great notes on Mitosis and Meiosis. Theyre very clear and to the point. A honorable resource to utilize. Ill definitely be using it to admit from. thank :) For the Mitosis part, you could have added in something abou the semi-permable memeberne and the high to low consitration gradient. still they are well(p) notes and i asure you this is going in my favourites! :-) this stuff is forever on my test ;-) - only animal cells has centrioles - in cytokinesis lay down cell has a cell plate form because cell wall cant split besides that, this note is pretty good two thumbs up Clear notes that explain differences between the two divisions. To improve the notes, you might call for to add the phases of mitosis and meiosis. If you want to guide a full essay, tell it on our website: BestEssayCheap.com
