Mitosis and Meoisis Flashcards
What is mitosis used for?
To grow and replace cells that have been damaged
What are the main processes in the cell cycle of mitosis?
Interphase Prophase Metaphase Anaphases Telophase Cytokinesis
What happens during interphase?
It increase the amount of subcellular structures and then duplicates its DNA.
What happens during prophase?
The chromosomes lie free in the cytoplasm because the nucleus breaks down
What happens during metaphase?
The chromosomes line up at the centre of the cell
What happens during anaphase?
Cell fibres pull the chromosomes apart
What happens during telophase?
Membranes from around each of the sets of chromosomes- the nucleus has divided
What happens during cytokinesis?
The cytoplasm and cell membrane divide to form two separate cells
What is produced at the end of mitosis?
Two new daughter cells- they are genetically identical diploid cells
What is the stages of meiosis?
- It duplicates its DNA
- The chromosomes line up in pairs the centre of the cell
- The pairs are pulled apart so each new cell has one copy of each chromosome
- Each cell will have a mixture of the mother’s and father’s chromosomes
- The chromosomes line up again the centre of the cell
- You end up with four haploid daughter cells called gametes
Are the gametes genetically the same or different
They are genetically different.
