The Cell Cycle
Flashcards do conjunto (9)
- 1Do cells divide continuously or not?They do not divide continuously
- 2What happens during interphase of the cell cycle (hint- not mitosis).first growth (proteins are synthesised and produced), synthesis (DNA is replicated) and second growth (organelles grow and divide).
- 3What are the three phases of the cell cycleinterphase
nuclear division
cell division - 4Describe nuclear divisionwhen the nucleus either divides into two (mitosis) or four (meiosis)
- 5describe cell divisionfollows nuclear division in that the whole cell either divides into two (mitosis) or four (meiosis)
- 6What can you say about the length of each cell cycle?varies among different organisms, typically a mammalian cell takes around 24 hours to divide, 90% of this time being interphase
- 7What is cancerA group of cells that divide rapidly and uncontrollably as a result of damage to the genes that regulate mitosis and the cell cycle.
- 8What is involved in the treatment of cancer?Blocking of cell division in order to stop the growth of cells.
- 9How does chemotherapy work?prevents DNA from replicating, it inhibits the metaphase stage of the cell cycle by interfering with spindle formation.
