mitosis Flashcards
what is mitosis?
a type of nuclear division carried out by diploid body cells
what happens to the cell nucleus?
it divides into two
what are the daughter cells like?
genetically identical to eachother
what number of chromosomes do the daughter cells have?
diploid- 46
what is mitosis required for?
growth
repair of damaged tissue
asexual reproduction
what happens before mitosis must occur?
these chromosomes must be replicated to double the amount of genetic material in the nucleus
what happens to the chromosomes after they are replicated?
they now appear as X shapes
what happens to the X shaped chromosomes?
they are then pulled apart- one half of each being pulled to either end of the cell
what happens once the chromosomes are pulled to separate ends of the cell?
the cytoplasm and membrane split- resulting in two genetically identical diploid daughter cells which contain the same chromosome number as the parent cell
