tell me difference between meosis and mitosis.. Atleast 8 points
Answers
Mitosis
Interphase – DNA has been replicated but Chromosomes not yet visible.
Prophase – Chromosomes condense and thicken, Each duplicated chromosome appear as two identical sister chromatids. The mitotic spindle begins to form.
Metaphase -The chromosomes assemble at the equator = metaphase plate.
Anaphase – The spindle fibres begin to contract. This starts to pull the sister chromatids apart. At the end of anaphase a complete set of daughter chromosomes is found each pole.
Type of reproduction: Sexual.
Occurs in: Humans, animals, plants, fungi.
Function: Genetic diversity through sexual reproduction.
Meiosis
Interphase: Each chromosome replicates.The result is two genetically identical sister chromatids.
Prophase I (Crossing-over recombination) Homologous chromosomes (each consisting of two sister chromatids) come together as pairs The structure formed is called a tetrad. Chromosome segments are swapped between non-sister chromatids at crossover points called chiasmata (= crossing-over).
Metaphase I Chromosomes align on the metaphase plate. Chromosomes still arranged as: pairs of homologues.
Anaphase I Sister chromatids remain attached. But homologous chromosomes move apart to opposite poles.
Type of reproduction: Asexual
Occurs in : All Organisms
Function: Cellular reproduction and general growth and repair of the body.
