The Cell Cycle and Mitosis
Flashcards do conjunto (13)
- 1What two main phases make up the cell cycle?Interphase
M phase - 2What is interphase?A period of cell growth and DNA replication.
- 3What is the M phase?A period of cell division (involves mitosis and cytokinesis)
- 4What regulates the cell cycle?Checkpoints
- 5Complete the sentences: During ______________ the cell caries out normal functions and prepares to divide. The cell's DNA is _________ and __________, and the organelles are also replicated,During INTERPHASE the cell caries out normal functions and prepares to divide. The cell's DNA is UNRAVELLED and REPLICATED, and the organelles are also replicated,
- 6TRUE OR FALSE: The ATP content of the cell during interphase is increasedTRUE
- 7What are the uses of mitosis?Growth
Repair
Asexual reproduction - 8What are the 4 stages of mitosis?Prophase
Metaphase
Anaphase
Telophase - 9What happens in prophase?Chromosomes condense
Centrioles move to poles of cell
Nuclear envelope breaks down - 10What happens in metaphase?Chromosomes line up at the spindle equator
Spindle fibres attach to the centromeres
- 11What happens in anaphase?Centromeres divide, separating each pair of sister chromatids
Spindles contract, pulling chromatids to opposite ends of the cell
- 12What happens in telophase?Chromatids uncoil (now called chromosomes again)
Nuclear envelope forms
- 13What happens in cytokinesis?Cytoplasm divides
There are now 2 identical daughter cells
Begins in anaphase, ends in telophase
Separate process to mitosis
