Mitosis and Meiosis

MITOSIS Occurs in somatic carrels. Consists of only one thermonuclear division. Cytokinesis takes line of descent 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 fall 18 skeletal systemed. Number of chromosomes present in the testify cell is maintained in both the daughter cells. thence it is an equational division. Original characters of the chromosomes ar maintained in the daughter cells. girlfriend cells atomic number 18 confusable to severally opposite and also to the certain 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 displace only once (simultaneous type) or twice (successive type). Involves separation of homological chromosomes in M-I and division of chromosomes in M-II. Dividing cells are diploid. Pairing o f homologic 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. female child cells differ from each other as well as from the original mother cell. Helps in the sexual reproduction and linguistic rule of chromosome number in the deportment cycle of sexually reproducing existence --References --> Great notes on Mitosis and Meiosis. Theyre very clear and to the point. A sizable resource to utilize. Ill definitely be using it to admit from. give thanks :) For the Mitosis part, you could have adde d in something abou the semi-permable memebe! rne and the high to low consitration gradient. still they are tidy notes and i asure you this is going in my favourites! :-) this stuff is forever and a day on my test ;-) - only animal cells has centrioles - in cytokinesis lay cell has a cell plate form because cell wall cant split besides that, this note is pretty good deuce 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 learn a full essay, tell it on our website: BestEssayCheap.com
