Vocab
Form of DNA when not dividing
In loose spaghetti form
What is Chromatin?
46
How many chromosomes do humans have?
PMAT
What is a good memory device to remember the stages of mitosis in order?
Meta - Middle
What is a good memory device for Metaphase?
G1
S-synthesis
G2
What are the three phases of interphase?
Condensed form of DNA during division that is organized
DNA is wrapped around proteins
What are chromosomes?
The two parts of a chromosome seperated by the centromere region. One is long and other is short.
What are the long and short chromosome arms?
Prophase
Metaphase
Anaphase
Telophase
What are the 4 stages of mitosis in order?
Chromosomes line up at the center of the cell
What happens in metaphase?
The part of interphase when the cell begins to grow after mitosis
What is G1?
The two separate parts of a chromosome in the early stages of mitosis
What are Chromatid?
The space between the long chromosome arm and short chromosome arm that allows the spindles to easily be attached for division.
What is the centromere region?
The stage in which chromosomes condense and become visible, nuclear envelope breaks down and spindle begins to form
What is prophase?
Ana - Away
What is a good memory device for anaphase?
The part of interphase when the chromosomes are copied preparing for mitosis.
What is s-synthesis phase?
The part of the cell cycle before mitosis in which the cell grows and replicates DNA
What is interphase?
The fibers that connect from the centriole to the chromosomes during division. Used to split the chromosomes. Long cellular beams.
What are spindles?
The stage in mitosis where the chromosomes separate from each other and move towards opposite poles
What is anaphase?
The division of the cytoplasm after telophase. Creates two separate cells.
What is cytokinesis?
The part of interphase where the cell begins to grow again before mitosis
What is g2?
The term given to the life of a cell including interphase (growth) and mitosis (division)
What is the cell cycle?
The way DNA is arranged before division in order to be more organized into chromosomes. Resembles thread around a spool. This part is the spool the thread or DNA wraps around.
What are nucleosomes?
The final phase in which the cell begins to divide into two daughter cells, rebuilds nuclear envelope and takes chromosomes back into chromatin form. Prepares to split into two cells
What is Telophase?
Plant cells form a new cell wall or cell plate in the middle of the cell
Animal cells have a protein ring around the middle of the cell which pinches down to break into two cells
How is cytokinesis different in animal and plant cells?
G1 - 4h
S - 10h
G2- 4h
Mitosis - 2h
What are the general lengths of each of the parts in the cell cycle?
