CB2a- mitosis

Cards (12)

what is mitosis?
cell division process which produces 2 identical diploid cells
what are the different stages
Interphase
Prophase
Metaphase
Anaphase
Telophase
Cytokineses
what happens in interphase?
DNA in chromosomes replicates itself ready for mitosis
what happens in prophase? 
the DNA in chromosomes and their copies condenses to become more visible.
the membrane around the nucleus disappears
what happens in metaphase?
chromosomes and their copies line up in the middle of the cell.
what happens in anaphase?
chromosomes separate and move to opposite poles of the cell.
what happens in telophase?
new membranes form around the chromosomes at each end of the cell.
what happens in cytokinesis?
cell division, specifically the division of the cytoplasm and organelles, resulting in two daughter cells.
why is mitosis important for an organism?
-growth
-repair
-asexual reproduction
why may organisms rely on asexual reproduction?
numerous of offspring produces quickly, no needing to find a mate, genetic continuity
how does mitosis produce genetically identical, diploid cells?
the cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.
how do cancers grow?
uncontrolled cell division, a group of cancerous cells are called a tumour
