Mitosis
The phase in mitosis when sister chromatids separate
Anaphase
The process by which gametes are produced
What is meiosis?
50
The number of cycles that meiosis goes through.
What is two?
S phase
Undifferentiated cells
STEM Cells
the longest phase in mitosis where chromosomes condense, the nuclear membrane disappears, and the centrioles appears?
what is prophase?
The process in meiosis that ensures more genetic variation
Occurs in prophase 1
What is crossing over?
The part of the chromosome that hold sister chromatids together
What is a centromere?
In polar bears, male gametes have 15 chromosomes. How many chromosomes will the stem cell have?
30
What type of cells does mitosis occur
body cells or autosomes
How many times does cytokinesis occur during meiosis?
2
Which phase in interphase are cells in when they are not dividing?
G1
What happens during prophase II of mitosis?
There is no prophase II in mitosis.
Only prophase
The stage in mitosis that the cell spends the most time in
Prophase
Which phase of meiosis I do homologous chromosomes line up at the equator (middle) of the cell?
Metaphase 1
Name the term for the cells of normal body cells.
What are autosomes?
Identify the 3 checkpoints and explain what happens
G1- Check for growth, duplication of organelles, food, and energy
G2-Correct DNA replication
M- Checks to see if the spindle fibers are attached to the chromosome at the centromere.
If a chemical is added to a cell that prevents the breakdown of the nuclear membrane, which phase in mitosis and meiosis can not occur?
What is prophase (mitosis), prophase I (Meiosis I) , and prophase II (Meiosis II) ?
