Mitosis/Meiosis
The process that results in new cells with genetic material that is identical to the original cell
What is mitosis
How many pairs of chromosomes do humans have?
23 pairs
Two sets of chromosomes is called
What is diploid?
Name all 4 phases
Prophase, Metaphase, Anaphase, Telophase
The number of cycles (PMAT) that meiosis goes through.
What is two?
These help pull the chromosomes and/or chromatids apart in anaphase
What are spindle fibers
the phase when chromosomes/chromatids pull apart toward the edge of the cell
What is anaphase?
True or False: The order of the phases does not matter
The purpose of meiosis
To create reproduction cells
How many total chromosomes do we have?
46 chromosomes
the phase where chromosomes reach the edges of the cell and two new nuclei form
What is telophase?
What is the difference in Metaphase 1 and Metaphase 2 in Meiosis?
In 1 they line up in pairs in the middle, in 2 they are in a single file line
The process that results in genetically different cells than the original cell
What is meiosis?
True or False: Our cells are always in Mitosis or Meiosis
False: A cell only spends a small portion of it's living replicating and dividing
The DNA or genetic material is called
Chromosomes
the phase where the cell spends a majority (90%) of its life
What is interphase
True or False: Mitosis goes through PMAT once
True!
The purpose of mitosis
Growth and repair
How many new cells do we end with in Meiosis?
4 New Cells
Define Chromatid / Chromatin
Half of a chromosome
the phase where chromosomes thicken and become visible
What is prophase?
What is the difference in Anaphase 1 and Anaphase 2 in Meiosis?
In 1 they chromosomes are pulled apart, in 2 the chromatids are pulled apart
