Meiosis
What kind of cells are involved in meiosis?
Eukaryotes
Does binary fission involve prokaryotes or eukaryotes?
Prokaryotes
What kind of cells are involved with mitosis?
Eukaryotes
What are the two major stages of the cell cycle?
Interphase and mitosis
What are the two types or forms of DNA?
Chromatin and Chromosomes
What kind of reproduction does meiosis involve?
Sexual reproduction
What kind of organism uses binary fission?
Bacteria
What kind of reproduction happens in mitosis?
Asexual reproduction
What are the 3 stages of interphase and what does each stage do?
1. G1 stage - growth, prep for synthesis
2. S stage - synthesis of DNA
3. G2 stage - growth, prep for division
True or False: Both chromatin and chromosomes have DNA and protein.
True
What 4 stages occur during meiosis?
Prophase, metaphase, anaphase, and telophase
What kind of reproduction occurs during binary fission?
Asexual reproduction
How many chromosomes do we start with in our cells?
46 chromosomes
What is the first stage of mitotic cell division and what happens in this stage?
Prophase - spindle apparatus forms, chromatin condenses into chromosomes, nucleus breaks down
Which form of DNA is visible under a light microscope?
Chromosomes
Haploid cells
What is the first step in binary fission?
Duplication of chromosomes
What stages involve mitosis?
Prophase, metaphase, anaphase, and telophase
What is the second stage of mitotic cell division and what happens in this stage?
Metaphase - chromosomes line-up at cell's equator
True or False: Chromatin is tightly packed together.
False; loosely
How many times does a cell divide in meiosis?
Two times
The two cells in the end of binary fission are called what?
Daughter cells
What is the goal of mitosis?
Each daughter cell has a perfect, full set of chromosomes
What is the third and fourth stage of cell division and what happens in these stages?
Anaphase - spindle contracts at both ends, pulls apart sister chromatids, one copy is pulled in each direction
Telophase - spindle breaks down, nucleus reforms, DNA uncoils from chromosome back into chromatin, cytokinesis
Which form of DNA happens in cell division only?
Chromosomes
