Question

What is the difference between meiosis and mitosis?

Answer 1

uhm...yeah.

Answer 2

well there is differences ill write a summary for each one and u will see for urself!!

Answer 3

-meiosis


prophase 1 :
*homologous chromosomes pair, forming a bivalent . (note. the bivalent has two chromosomes and four chromatids.)

metaphase 1.

*nuclear membrane disappears.
* bivalents align at the metaphase plate
*spindle fibers attach to the chromosomes at the centromeres.

Answer 4

anaphase 1:
* homologous chromosomes (made of 2 chromatids) are pulled by the spindle fibers to opposite sides of the cell

Answer 5

telophase 1.

*nuclear membrane reforms
* the cell splits into two cells

Answer 6

prophase 2 :
* nuclear membrane fades
*spindle fibers reform between centrioles
* the chromosomes condense thus become visible.

Answer 7

metaphase 2:
*the chromosomes line at at the metaphase plate
* nuclear membrane disappears
*spindle fibers attach to the chromosome at the centromere

Answer 8

anaphase 2:
*sister chromatids separate and are moved to opposite sides of the cell

Answer 9

telophase 2 :
* spindle fibers disintegrate
*cell starts to split into two
*a nuclear membrane forms around each set of chromatids
*the chromatids become the chromosomes of the daughters cell
* four new cells are formed

Answer 10

and a meiosis is a cell division where by one cell divides into four new cells (gametes)

Answer 11

-mitosis
interphase:

* each chromosomes replicates it forms an exact copy of itself
*centrioles(organelles that produce thread like structures, called spindle fibers) duplicate.

Answer 12

prophase:

* the chromosomes condense and thus become visible
* the two pairs of centrioles move to opposite sides of the cell and spindle fibers start to form between them.
*the nuclear membrane starts to disintegrate

Answer 13

anaphase:

*sister chromatids separate and move to opposite sides of the cell

Answer 14

telophase:
* spindle fibers disintegrate
*cell starts to split into two
* a nuclear membrane forms around each set of chromatids
* the chromatids become the chromosomes of the daughter cell .

Answer 15

and a mitosis is a cell splits into identical cells (mitosis only works for the a sexual reproduction and the meiosis for sexual reproduction)

if u didnt understand just look at this video ^^

but i hope u will understand!!!! :D

Answer 17

In mitosis, think "body cells." You end up with two cells that are genetically the same as the cell that produced them and to each other. (One cell, 2n chromosomes -> 2 cells, 2n chromosomes). In meiosis, the words "sex cells" should pop to mind. You start with one cell and, through meiosis I and meiosis II, will end up with four cells that are genetically unique. (One cell, 2n chromosomes->Four cells, n chromosomes).

Answer 18

mitosis= 2 new cells, full set dna
meiosis=2 new cells, half set dna each

Answer 19

mitosis is for the normal cells, meiosis is for sex- like sperm and eggs

Answer 20

the main difference is that in meiosis, an haploid cell (n) is formed and in mitosis, a diploid cell (2n) is formed..hope that helped...
