Cell Cycle Flashcards
(28 cards)
Mitosis happens in what type of cell
Mitosis happens in a somatic cells all cells of your body except gametes
Mitosis
The division of the nucleus of the cell into two new nuclei(identical copy)
Interphase
The beginning of the cell cycle G1, S, G2
G1 phase
Growth one cell has normal operations
S-phase
Synthesis phase DNA makes a copy of itself
G2 phase
Growth to cell prepares to divide
Prophase
Nuclear membrane disappears chromatin changes to chromosomes spindle fibers up here spindles will help separate chromatids
Metaphase
The chromosomes line up at the equator
Anaphase
Sister chromatids separate..
spindle fibers shorten to do this
Telophase
Reverse of prophase
Nuclear membrane reappears chromosomes return to chromatin spindle fibers disappear
Cytokinesis
Cytokinesis is the final step is when the cytoplasm divides
Cytokinesis in animals
Animal cells have no wall
A cleavage furrow forms
the cell splits
Cytokinesis in plants
A cell plate forms between the two cells
the cell plate will become the cell wall for both
In order list the four stages of mitosis
Prophase metaphase anaphase telophase then cytokinesis
What are the steps involved in interphase
G1 S G2
What is the end result of the cell cycle
Two new identical cells are formed
What type of cells does this occur in
Somatic cells or body cells
What’s a way to remember the order of mitosis
Pittsburgh makes another touchdown
What never occurs and interphase
Cell division
Where are chromatids found
Nucleus
Chromatids are connected by
The centromere… And they have a long and short arm
What phase do most cells spend the majority of their lifetime
Interphase
What does S phase stand for
Synthesis phase
What are the new cells called
Daughter cells
