Mitosis Flashcards
(13 cards)
What is mitosis?
cell division that produces two genetically identical daughter cells.
Why is mitosis important?.
allows growth, repair of tissues, and asexual reproduction.
What happens during the interphase?
The cell grows and DNA is replicated (copied).
What happens during prophase
Chromosomes condense and become visible; nuclear membrane breaks down.
What happens during metaphase?
Chromosomes line up in the middle of the cell on its equator
What happens during anaphase?
Chromosomes are pulled apart to opposite ends of the cell.
They are pulled by spindle fibres
What happens during telophase?
Nuclear membranes form around each set of chromosomes.
What is cytokinesis?
The cytoplasm divides, creating two separate daughter cells.
How many daughter cells does mitosis produce? Two daughter cells.
Two daughter cells.
G1 phase (Gap 1)
The cell grows and carries out normal functions. It also prepares for DNA replication.
S phase (Synthesis)
The cell copies (replicates) its DNA, so there are two complete sets of chromosomes.
G2 phase (Gap 2)
The cell continues to grow and prepares for mitosis. It checks that DNA replication is complete and repairs any damage.
M phase (Mitosis)
The cell divides its nucleus (mitosis) and then the cytoplasm (cytokinesis) to form two daughter cells.
