Interphase
Mitosis
Cytokinesis
Cellular Growth
Cancer
100
The phase where the Cell spends the most time.
What is interphase?
100
The process during cell division in which the nucleus of a cell is divided into two nuclei. Makes an identical copy of another cell.
What is Mitosis?
100
The process in which the cytoplasm divides.
What is cytokinesis?
100
The life of a cell is shown as a cycle, a repeating sequence of ___________ and division.
What is cellular growth?
100
A normal cell that has lost control.
What is a cancer cell?
200
G1, S, and G2.
What are the stages of Interphase?
200
Prophase, prometaphase, metaphase, anaphase, and telophase.
What are the stages of mitosis?
200
This is the cellular division and the dividing of the cytoplasm and all of its contents.
What is the purpose of cytokinesis?
200
Cellular checkpoints; Cell growth checkpoint (G1), DNA Synthesis (G2) checkpoint, Mitosis checkpoint
What tells the cell to divide?
200
A bunch of cancerous cells grouped together.
What is a tumor?
300
DNA is copied and EACH chromosome consists of two chromatids attached at the centromere.
What is S (synthesis phase)?
300
When chromosomes line up down the middle of the cell.
What is metaphase?
300
Doesn't separate but stays attached and is separated by a cell wall.
What is cytokinesis in a plant cell?
300
If the cell passes this check point, then it moves on to the G1 phase
What is the Mitosis checkpoint
300
Tumor-suppressor genes and prono-oncogenes.
What are two types of genes that can cause cancerous cells?
400
Preparations are made for the nucleus to divide and Microtubules are assembled.
What is G2 (second growth phase)?
400
New nuclear membranes start to form and the cell starts entering cytokonesis.
What is telophase?
400
It grows and separates as if a belt is being wrapped around it and it keeps tightening until the 2 daughter cells break apart.
What is cytokinesis in an animal cell?
400
If conditions are good, then the cell moves on to the S phase. If conditions are not favorable, the cell cycle will stop, leading the cell to apoptosis.
What is the Cell growth checkpoint (G1)
400
Density independent, anchorage independent, immortal - they divide indefinitely.
What are the characteristics of a cancerous cell?
500
Cell grows rapidly and occupies major portion of the cell’s life.
What is G1 (first growth phase)?
500
When the nuclear membrane dissolves, the chromosomes shorten and condense, and the centrioles start creating spindle fibers.
What is Prophase?
500
Usually occurs between late anaphase and end of telophase.
What is the beginning of cytokinesis?
500
This is when DNA replication is checked by repair enzymes. If this is passed, the proteins will help trigger mitosis.
What is the DNA Synthesis (G2) checkpoint
500
Prevents the development of many cells that contain mutations. For example, p53 halts cell division if damaged DNA is detected.
What are tumor suppressor genes?
