Mitosis:
*Identical daughter cells
*cytokinesis separates cell into two cells
*makes diploid cells
Meiosis:
*Two processes (Meiosis 1 and Meiosis 2)
,9/16/25, 5:36 PM BIO 134 Exam 2 Practice
*Daughter cells (gametes) that are different from parent cell
*Meiosis 1, cytokinesis does not separate the cell
*Homologous pairs separate in Meiosis Metaphase 1
*Makes haploid cells
Both:
*uses prophase, metaphase, anaphase, and telophase
*chromosomes replicate in S phase
Give this one a try later!
compare and contrast the
ID the phases of the cell cycle. what
processes of mitosis and
happens in each phase? what is the
meiosis. how are they similar
goal of the cell cycle?
and different?
at the end of G2, what must happen True or False:
in order for mitosis to proceed The process of splitting the two new
correctly? cells apart is known as cytokinesis.

Both:

*chromosomes replicate in S phase
*these checkpoints occur at G1, G2, and M (metaphase).
*cell cycle checkpoints are restriction points that make sure cell has proper
condition to divide.
*platelet- derived growth factors is required for cell division and pushes the
cell past the G1 checkpoint.
*The cell will either enter Go if it can not push through and fix itself or it will
die
*cyclin- CDK complex
mitosis came from binary fission in prokaryotes. eukaryotes with nuclear
envelopes and larger genomes developed the process of mitosis.
dinoflagellates and yeast go through "intermediate mitosis"; their
nuclear envelopes do not fragment, unlike mitosis. chromosomes divide
and separate within the nucleus and use microtubules
Evolution of Mitosis -
We can hypothesize that mitosis evolved from simpler prokaryotic cell
reproduction since some proteins involved in bacterial binary fission are
similar to eukaryotic proteins in mitosis.

- Possible intermediate stages in the evolution of mitosis might be
found in dinoflagellates, diatoms and some yeasts.
- In these types of nuclear division, the nuclear envelope remains intact
in contrast to what happens in most eukaryotic cells.
chromatid is a pair of identical chromosomes 8
chromatid is the chromosome put together 88
*chromosomes are visible during prophase and metaphase
*chromatids are visible during anaphase and telophase
*sister chromatids are seen during pro metaphase, metaphase, and anaphase
