Cell cycle Flashcards
To memorize and familiarize the cell cycle (36 cards)
Once a cell is fully grown, it either stops growing or divides and produces more cells through a process called
Cellular Reproduction
Helps your body grow and repair worn-out tissues.
Cellular Reproduction
Cells follow a cycle of growing and dividing known as the
Cell cycle
Every time a parent cell undergoes the cell cycle, it produces
New daughter cells
Two main stages in the cell cycle
Interphase and cell division
Preparation for Cell Division
Interphase
Cells grows, copies organelles, and makes molecular blocks
G1 or First gap
Cell synthesizes a complete copy of DNA, and duplicates the centrosome
S phase
Microtubule-organizing structure that helps separate DNA during M phase
Centrosome
The cell grows more, makes proteins and organelles, and begins to reorganize its contents in preparation for Mitosis.
G2 or Second Gap
Cell division(Mitosis, Meiosis)
M phase
Two types of cell division
Mitosis and Meiosis
Is used when a cell needs to be replicated into exact copies of itself.
Mitosis
The two new cells have the same DNA, functions, genetic code, and a number of chromosomes.
Mitosis
The original cell
Mother
Two new cells are called
Daughter cells
How many chromosomes are in daughter cells?
23 pairs of chromosomes
Happens with somatic or body cells such as cells of the skin, blood, and muscles.
Mitosis
Acronym for the stages in Mitosis
PMAT
Stages in Mitosis
Prophase, Metaphase, Anaphase, Telophase
Chromatin condenses into chromosomes and the nuclear membrane and nucleolus break down
Prophase
The chromosomes line up along in the middle of the cell
Metaphase
The chromosomes separate and move to the opposite sides of the cell
Anaphase
The splitting of cells
Cytokinesis
