What are the three phases that make up Interphase?
G1, Synthesis, G2
What are the two phases that make up the cell cycle?
Interphase and Mitosis.
What is the structures that hold together sister cromatids?
Centromere
What is the uncontrolled division of cells resulting in a malignant growth?
Cancer
Each chromosome consists of 2?
sister chromatids
What are the phases that make up Mitosis?
PPMAT- Prophase, Prometaphase, Metaphase, Anaphase, Telophase, and Cytokinesis.
During cytokinesis what happens in animals and plants;
Animals; a cleavage furrow separates the daughter cells.
Plants; a cell plate separates the daughter cells.
What is the football shaped structures consisting of thin fibers?
Spindle
What causes cancer in mitosis?
The normal 'checkpoints' regulating mitosis are ignored or overridden by the cancer cell. Cancer begins when a single cell is transformed, or converted from a normal cell to a cancer cell.
What is the phase in which the DNA is being replicated?
Synthesis
What step is Interphase and what happens in it?
Interphase is the 4th step of mitosis. In Anaphase, the sister chromatids (now called chromosomes) are pulled towards opposite poles.
Chromosomes arrive at opposite poles and begin to decondense, Nuclear envelope material surrounds each set of chromosomes, and the mitotic spindle breaks down.
Telophase
What are the dark staining structures that carry the genetic material?
Chromosomes
What structure is responsible for moving the chromosomes during mitosis?
The bipolar spindle
Cytokinesis begins in which phase?
Telophase
What is Metaphase?
In metaphase, the chromatids line up at the center of the equator.
What are the 3 phases of Interphase in order?
G1 (cell growth), S phase (DNA synthesis), and G2 (cell growth).
Sister Chromatids
What are the two halves of a doubled chromosome structure?
What is the shortest phase of mitosis?
Anaphase or Telophase
Which of the following is NOT part of the chromosome?
kinetochore
chromatid
centromere
spindle
Spindle
What is the number of phases that make up Interphase?
3
What is C in the picture?
What are the t-shaped structures involved in the development of spindle fibers?
Centriole
During what phase do centrioles become visible?
During prophase, the nuclear envelope and nucleolus are dissolved and the chromosomes condense. The centrioles and spindle fibers begin to form at opposite poles of the cell
A cell that has 20 chromosomes undergoes mitosis. Which of the following is true?
two daughter cells will be created, each have 20 chromosomes
two daughter cells will be created, each have 40 chromosomes
4 daughter cells will be created, each having 10 chromosomes
2 daughter cells will be created, each having 10 chromosomes
two daughter cells will be created, each have 20 chromosomes
