Cell Cycle Basic
This phase is when the cell grows and copies its DNA
What is interphase?
Chromosomes condense and become visible during this phase.
What is prophase?
A structure made of DNA and proteins that carries genetic information.
What is a chromosome?
If cell cycle control fails, this disease may develop.
What is cancer?
Mitosis is important for growth and this process after injury.
What is repair (healing)?
What is the final growth phase of interphase?
What is G2?
Chromosomes line up in the middle of the cell.
What is metaphase?
Two identical copies of a chromosome attached at the center are called these.
What are sister chromatids?
This checkpoint ensures DNA is copied correctly before mitosis begins.
What is G2?
Skin cells divide frequently because they are constantly being this.
What is being shed/lost?
The stage where DNA replication occurs.
What is S phase?
Sister chromatids separate and move to opposite poles.
What is anaphase?
The region that holds sister chromatids together.
What is a centromere?
This checkpoint makes sure the cell is large enough and has enough nutrients before copying its DNA.
What is G1?
Unlike mitosis, this process produces gametes.
What is Meiosis?
Cells spend most of their life in this stage.
What is interphase?
Nuclear membranes reform around chromosomes.
What is telophase?
The difference between a chromatid and a chromosome is this:
A chromatid is one half of a duplicated chromosome; a chromosome can be single or duplicated.
If a cell has damaged DNA and does not fix it, the cell cycle should do this to protect the body.
What is a stop or apoptosis?
Uncontrolled mitosis can lead to this type of growth.
What is a tumor?
This phase includes mitosis and cytokinesis.
What is the M phase?
The division of the cytoplasm into two separate cells.
What is cytokinesis?
The number of chromosomes in human body cells.
What is 46?
If spindle fibers are not properly attached to chromosomes, the cell will not move on to this next phase.
What is anaphase?
Chemotherapy works by targeting these types of cells.
What are rapidly dividing cells?
